lt6202/LT6203/lt6204 1 620234fa the lt ? 6202/LT6203/lt6204 are single/dual/quad low noise, rail-to-rail input and output unity gain stable op amps that feature 1.9nv/ ? hz noise voltage and draw only 2.5ma of supply current per amplifier. these amplifiers combine very low noise and supply current with a 100mhz gain bandwidth product, a 25v/ m s slew rate, and are optimized for low supply signal conditioning systems. these amplifiers maintain their performance for supplies from 2.5v to 12.6v and are specified at 3v, 5v and 5v supplies. harmonic distortion is less than C 80dbc at 1mhz making these amplifiers suitable in low power data acquisition systems. the lt6202 is available in the 5-pin sot-23 and the 8-pin so, while the LT6203 comes in 8-pin so and msop pack- ages with standard op amp pinouts. for compact layouts the LT6203 is also available in a tiny fine line leadless package (dfn), while the quad lt6204 is available in the 16-pin ssop and 14-pin so packages. these devices can be used as plug-in replacements for many op amps to improve input/output range and noise performance. n low noise, low power signal processing n active filters n rail-to-rail buffer amplifiers n driving a/d converters n dsl receivers n battery powered/battery backed equipment , ltc and lt are registered trademarks of linear technology corporation. n low noise voltage: 1.9nv/ ? hz (100khz) n low supply current: 3ma/amp max n gain bandwidth product: 100mhz n dual LT6203 in tiny dfn package n low distortion: C80db at 1mhz n low offset voltage: 500 m v max n wide supply range: 2.5v to 12.6v n input common mode range includes both rails n output swings rail-to-rail n common mode rejection ratio 90db typ n unity gain stable n low noise current: 1.1pa/ ? hz n output current: 30ma min n operating temperature range C40 c to 85 c single/dual/quad 100mhz, rail-to-rail input and output, ultralow 1.9nv/ ? hz noise, low power op amps low noise 4- to 2-wire local echo cancellation differential receiver line receiver integrated noise 25khz to 150khz bandwidth (khz) 0 integrated noise ( v rms ) 5.0 4.5 4.0 3.5 3.0 2.5 2.0 1.5 1.0 0.5 0 40 80 100 6203 ?ta01b 20 60 120 140 160 1:1 v l 100 line 50 50 1k 1k v r line receiver 2k 1k 1k 2k 6203 ta01a + + + + v d line driver 1/2 LT6203 1/2 LT6203 1/2 lt1739 1/2 lt1739 applicatio s u features typical applicatio u descriptio u

lt6202/LT6203/lt6204 15 620234fa amplifier characteristics figure 1 shows a simplified schematic of the lt6202/ LT6203/lt6204, which has two input differential amplifi- ers in parallel that are biased on simultaneously when the common mode voltage is at least 1.5v from either rail. this topology allows the input stage to swing from the positive supply voltage to the negative supply voltage. as the common mode voltage swings beyond v cc C 1.5v, current source i 1 saturates and current in q1/q4 is zero. feedback is maintained through the q2/q3 differential amplifier, but with an input g m reduction of 1/2. a similar effect occurs with i 2 when the common mode voltage swings within 1.5v of the negative rail. the effect of the g m reduction is a shift in the v os as i 1 or i 2 saturate. figure 1. simplified schematic applicatio s i for atio wu u u input bias current normally flows out of the + and C inputs. the magnitude of this current increases when the input common mode voltage is within 1.5v of the negative rail, and only q1/q4 are active. the polarity of this current reverses when the input common mode voltage is within 1.5v of the positive rail and only q2/q3 are active. the second stage is a folded cascode and current mirror that converts the input stage differential signals to a single ended output. capacitor c1 reduces the unity cross frequency and improves the frequency stability without degrading the gain bandwidth of the amplifier. the differential drive generator supplies current to the output transistors that swing from rail-to-rail. differential drive generator + r1 r2 r3 r4 r5 q2 q3 q5 q6 q9 q8 q7 q10 q11 q1 q4 i 1 i 2 d3 d2 d1 desd2 desd4 desd3 desd1 desd5 desd6 + v bias c m c1 +v +v +v +v ? ? ? v + v 6203/04 f01
lt6202/LT6203/lt6204 16 620234fa input protection there are back-to-back diodes, d1 and d2, across the + and C inputs of these amplifiers to limit the differential input voltage to 0.7v. the inputs of the lt6202/LT6203/ lt6304 do not have internal resistors in series with the input transistors. this technique is often used to protect the input devices from over voltage that causes excessive currents to flow. the addition of these resistors would significantly degrade the low noise voltage of these ampli- fiers. for instance, a 100 w resistor in series with each input would generate 1.8nv/ ? hz of noise, and the total amplifier noise voltage would rise from 1.9nv/ ? hz to 2.6nv/ ? hz. once the input differential voltage exceeds 0.7v, steady state current conducted though the protec- tion diodes should be limited to 40ma. this implies 25 w of protection resistance per volt of continuous overdrive beyond 0.7v. the input diodes are rugged enough to handle transient currents due to amplifier slew rate over- drive or momentary clipping without these resistors. figure 2 shows the input and output waveforms of the amplifier driven into clipping while connected in a gain of a v = 1. when the input signal goes sufficiently beyond the power supply rails, the input transistors will saturate. when saturation occurs, the amplifier loses a stage of phase inversion and the output tries to change states. diodes d1 and d2 forward bias and hold the output within a diode drop of the input signal. in this photo, the input signal generator is clipping at 35ma, and the output transistors supply this generator current through the protection diodes. with the amplifier connected in a gain of a v 3 2, the output can invert with very heavy input overdrive. to avoid this inversion, limit the input overdrive to 0.5v beyond the power supply rails. esd the lt6202/LT6203/lt6204 have reverse-biased esd protection diodes on all inputs and outputs as shown in figure 1. if these pins are forced beyond either supply, unlimited current will flow through these diodes. if the current is transient and limited to one hundred milliamps or less, no damage to the device will occur. noise the noise voltage of the lt6202/LT6203/lt6204 is equiva- lent to that of a 225 w resistor, and for the lowest possible noise it is desirable to keep the source and feedback resistance at or below this value, i.e. r s + r g || r fb 225 w . with r s + r g || r fb = 225 w the total noise of the amplifier is: e n = ? (1.9nv) 2 + (1.9nv) 2 = 2.7nv. below this resistance value, the amplifier dominates the noise, but in the resis- tance region between 225 w and approximately 10k w , the noise is dominated by the resistor thermal noise. as the total resistance is further increased, beyond 10k, the noise current multiplied by the total resistance eventually domi- nates the noise. the product of e n ? ? i supply is an interesting way to gauge low noise amplifiers. many low noise amplifiers with low e n have high i supply current. in applications that require low noise with the lowest possible supply current, this product can prove to be enlightening. the lt6202/LT6203/ lt6204 have an e n , ? i supply product of 3.2 per amplifier, yet it is common to see amplifiers with similar noise specifications have an e n ? ? i supply product of 4.7 to 13.5. for a complete discussion of amplifier noise, see the lt1028 data sheet. figure 2. v s = 2.5v, a v = 1 with large overdrive lt6202/03/04 f02 applicatio s i for atio wu u u ov
lt6202/LT6203/lt6204 17 620234fa low noise, low power 1m w ac photodiode transimpedance amplifier figure 3 shows the lt6202 applied as a transimpedance amplifier (tia). the lt6202 forces the bf862 ultralow- noise jfet source to 0v, with r3 ensuring that the jfet has an i drain of 1ma. the jfet acts as a source follower, buffering the input of the lt6202 and making it suitable for the high impedance feedback elements r1 and r2. the bf862 has a minimum i dss of 10ma and a pinchoff voltage between C0.3v and C1.2v. the jfet gate and the lt6202 figure 3. low noise, low power 1m w ac photodiode transimpedance amplifier figure 4. precision low noise, low power transimpedance amplifier output therefore sit at a point slightly higher than one pinchoff voltage below ground (typically about C0.6v). when the photodiode is illuminated, the current must come from the lt6202s output through r1 and r2, as in a normal tia. amplifier input noise density and gain- bandwidth product were measured at 2.4nv/hz and 100mhz, respectively. note that because the jfet has a high g m , approximately 1/80 w , its attenuation looking into r3 is only about 2%. gain-bandwidth product was mea- sured at 100mhz and the closed-loop bandwidth using a 3pf photodiode was approximately 1.4mhz. precision low noise, low power, 1m w photodiode transimpedance amplifier figure 4 shows the lt6202 applied as a transimpedance amplifier (tia), very similar to that shown in figure 3. in this case, however, the jfet is not allowed to dictate the dc-bias conditions. rather than being grounded, the lt6202s noninverting input is driven by the ltc2050 to the exact state necessary for zero jfet gate voltage. the noise performance is nearly identical to that of the circuit in figure 3, with the additional benefit of excellent dc performance. input offset was measured at under 200 m v and output noise was within 2mv p-p over a 20mhz bandwidth. + v bias philips bf862 r1 499k r2 499k c1 1pf v s v s + v out v s = 5v lt6202 r3 4.99k lt6202/03/04 f03 + v bias philips bf862 r1 499k r2 499k c1 1pf v s v s + v out v s = 5v r3 4.99k c2 0.1 f ltc2050hv r4 10m r5 10k c3 1 f lt6202/03/04 f04 + lt6202 typical applicatio s u
