thanks to their chopper architecture. ch opper-stabilized amps constantly correct low-frequency errors across the inputs of the amplifier. chopper-stabilized amplifiers ca n be explained with respect to: ? time domain ? frequency domain 4.1.1 time domain the basis of the chopper amplifier is realized in two steps. these steps are synchronized thanks to a clock running at 400 khz. figure 38. block diagram in the time domain (step 1) figure 39. block diagram in the time domain (step 2) figure 38 shows step 1, the first clock cycle, where v io is amplified in the normal way. figure 39 shows step 2, the second clock cycle, where chop1 and chop2 swap paths. at this time, the v io is amplified in a reverse way as compared to step 1. at the end of these two steps, the average v io is close to zero. the a2(f) amplifier has a small impact on the v io because the v io is expressed as the input offset and is consequen tly divided by a1(f). 9 r x w $ i ) l o w h u $ i 9 l q s 9 l q q & k r s &

before filtering is shown in figure 40 . figure 40. v io cancellation principle the low pass filter averages the output value resulting in the cancellation of the v io offset. the 1/f noise can be considered as an of fset in low frequency and it is canceled like the v io , thanks to the chopper technique. 4.1.2 frequency domain the frequency domain gives a more accurate vision of chopper-stabilized amplifier architecture. figure 41. block diagram in the frequency domain the modulation technique transpos es the signal to a higher frequency where there is no 1/f noise, and demodulate it back after amplification. 1. according to figure 41 , the input signal v in is modulated once (chop1) so all the input signal is transposed to the high frequency domain. 2. the amplifier adds its own error (v io (output offset voltage) + the noise v n (1/f noise)) to this modulated signal. 3. this signal is then demodulated (chop2 ), but since the noise and the offset are modulated only once, they are transposed to the high frequency, leaving the output signal of the amplifier without any offset and low frequency noise. consequently, the input signal is amplified with a very low offset and 1/f noise. 4. to get rid of the high frequency part of the output signal (which is useless) a low pass filter is implemented. to further suppress the remaining ripple down to a desired level, another low pass filter may be added externally on the output of the tsz121, tsz122, or tsz124 device. 6 w h s 6 w h s 6 w h s 6 w h s 6 w h s 6 w h s 9 l r 9 l r 7 l p h 9 l q q 9 l q s 9 r v

5.5 v. the parameters are fully specified for 1.8 v, 3.3 v, and 5 v power supplies. however, the parameters are very stable in the full v cc range and several characterization curves show the tsz121, tsz122, and tsz124 device characteristics at 1.8 v and 5.5 v. additionally, the main specifications are guaranteed in extended temperature ranges from -40 to +125 c. 4.3 input pin voltage ranges tsz121, tsz122, and tsz124 devices have internal esd diode protection on the inputs. these diodes are connected be tween the input and each supply rail to protect the input mosfets from electrical discharge. if the input pin voltage exceeds the power supply by 0.5 v, the esd diodes become conductive and excessive current can flow thro ugh them. without limitation this over current can damage the device. in this case, it is important to limit the current to 10 ma, by adding resistance on the input pin, as described in figure 42 . figure 42. input current limitation 4.4 rail-to-rail input

offset variation related to the offset value measured at 25 c . the operational amplifier is one of the main circuits of the signal conditioning chain, and th e amplifier input offset is a major contributor to the chain accuracy. the signal chain a ccuracy at 25 c can be compensated during production at application level. the maximum input voltage drift over temperature enables the system designer to anti cipate the effect of temperature variations. the maximum input voltage drift over temperature is computed using equation 1 . equation 1 where t = -40 c and 125 c. the tsz121, tsz122, and tsz124 datasheet maximum value is guaranteed by measurements on a representative sample size ensuring a c pk (process capability index) greater than 1.3. 4.6 rail-to-rail output the operational amplifier output levels ca n go close to the rails: to a maximum of 30 mv above and below the rail when connected to a 10 k resistive load to v cc /2. 4.7 capacitive load driving large capacitive loads can cause stability problems. incr easing the load capacitance produces gain peaking in the frequency resp onse, with overshoot and ringing in the step response. it is usually considered that with a gain peaking higher than 2.3 db an op amp might become unstable. generally, the unity gain config uration is the worst case for stability and the ability to drive large capacitive loads. figure 43 and figure 44 show the serial resistor that must be added to the output, to make a system stable. figure 45 shows the test configuration using an isolation resistor, riso. v io t ----------- - max

pcb layout recommendations particular attention must be paid to the layout of the pcb, tracks connected to the amplifier, load, and power supply. the power and ground traces are critical as they must provide adequate energy and grounding for all circuits. good practice is to use short and wide pcb traces to minimize voltage drops and parasitic inductance. in addition, to minimize parasitic impedance ov er the entire surface, a multi-via technique that connects the bottom and top layer ground pl anes together in many locations is often used. the copper traces that connect the output pins to the load and supply pins should be as wide as possible to minimize trace resistance. figure 43. stability criteria with a serial resistor at v dd = 5 v figure 44. stability criteria with a serial

recommended to place a 0.1 f capacitor as close as possible to the supply pins. a good decoupling has several advantages for an application. first, it helps to reduce electromagnetic interference. due to the modulation of the chopper, the decoupling capacitance also helps to reject the sm all ripple that may appear on the output. tsz121, tsz122, and tsz124 devices have been optimized for use with 10 k in the feedback loop. with this, or a higher value of resistance, these devices offer the best performance. 4.10 emi rejection ration (emirr) the electromagnetic interference (emi) rejection ratio, or emirr, describes the emi immunity of operational amplifiers. an adverse e ffect that is common to many op amps is a change in the offset voltage as a re sult of rf signal rectification. the tsz121, tsz122, and tsz124 have been sp ecially designed to mi nimize susceptibility to emirr and show an extremely good sensitivity. figure 46 shows the emirr in+ of the tsz121, tsz122, and tsz124

converted into voltage thanks to r resistance. this voltage is then amplified by tsz121, tsz122, and tsz124 devices (see figure 47 ). figure 47. oxygen sensor principle schematic the output voltage is calculated using equation 2 : equation 2 as the current delivered by the o2 sensor is extremely low, the impact of the v io can become significant with a tradit ional operational amplifier. the use of the chopper amplifier of the tsz121, tsz122, or tsz124 is perfect for this application. in addition, using tsz121, tsz122, or tsz124 devices for the o2 sensor application ensures that the measurement of o2 concentrat ion is stable even at different temperature thanks to a very good v io / t. 2 b v h q v r u 5 5 9 & & 7 6 = 7 6 = 7 6 = 9 r x w , v out i ( rv io ) r 2 r 1 ------ - 1 + ?? ?? ? =

mo st electronic systems. current sensing is useful for protecting applications. the low-side current sensing method consists of placing a sense resistor between the load and the circ uit ground. the resulting voltage drop is amplified using tsz121, tsz122, and tsz124 devices (see figure 49 ). figure 49. low-side current sensing schematic v out can be expressed as follows: equation 4 assuming that r f2 = r f1 = r f and r g2 = r g1 = r g , equation 4 can be simplified as follows: equation 5 the main advantage of using the chopper of the tsz121, tsz122, and tsz124, for a low- side current sensing, is that the errors due to v io and i io are extremely low and may be neglected. therefore, for the same accuracy, the shunt resistor can be chosen with a lower value, resulting in lower po wer dissipation, lower drop in th e ground path, and lower cost. particular attention must be paid on the matching and precision of r g1 , r g2 , r f1 , and r f2 , to maximize the accuracy of the measurement. 5 v k x q w 5 j 5 j & 5 i 9 9 r x w 5 i 7 6 = 7 6 = 7 6 = , , q , s v out r shunt i1 r g2 r g2 r f2 + ------------------------ - ? ? 1 r f1 r g1 --------- - + ?? ?? ? ? ? i p r g2 r f2 r
