7 applications information product description the el5106 and el5306 are fixed gain amplifier that offers a wide -3db bandwidth of 350mhz and a low supply current of 1.5ma. they work with su pply voltages ranging from a single 5v to 12v and they are also capable of swinging to within 1.2v of either supply on the output. these combinations of high bandwidth and low power make the el5106 and el5306 the ideal choice for many low- power/high-bandwidth applications such as portable, handheld, or battery-powered equipment. for varying bandwidth and higher gains, consider the el5191 with 1ghz on a 9ma su pply current or the el5162 with 300mhz on a 4ma supply current. versions include single, dual, and triple amp packages with 5 ld sot-23, 16-pin qsop, and 8 ld or 16 ld so outlines. power supply bypassing and printed circuit board layout as with any high frequency device, good printed circuit board layout is necessary for optimum performance. low impedance ground plane construction is essential. surface mount components are recommended, but if leaded components are used, lead lengths should be as short as possible. the power supply pins must be well bypassed to reduce the risk of oscillation. the combination of a 4.7f tantalum capacitor in parallel with a 0.01f capacitor has been shown to work well when placed at each supply pin. disable/power-down the el5106 and el5306 amplifiers can be disabled placing their output in a high impedance state. when disabled, the amplifier supply current is reduced to <25a. the el5106 and el5306 are disabled when its ce pin is pulled up to within 1v of the positive supply . similarly, the amplifier is enabled by floating or pulling the ce pin to at least 3v below the positive supply. for 5v supply, this means that the amplifier will be enabled when ce is 2v or less, and disabled when ce is above 4v. although the logic levels are not standard ttl, this choice of logic voltages allow the el5106 and el5306 to be enabled by tying ce to ground, even in 5v single supply applications. the ce pin can be driven from cmos outputs. gain setting the el5106 and el5306 are built with internal feedback and gain resistors. the internal feedback resistors have equal value; as a result, the amplifier can be configured into gain of +1, -1, and +2 without any external resistors. figure 13 shows the amplifier in gain of +2 configuration. the gain error is 2% maximum. figure 14 shows the amplifier in gain of -1 configuration. for gain of +1, in+ and in- should be connected together as shown in figure 15. this configuration avoids the effects of any parasitic capacitance on the in- pin. since the internal feedback and gain resistors change with temperature and pr ocess, external resistor should not be used to adjust the gain settings. figure 13. package power dissipation vs ambient temperature typical performance curves (continued) ambient temperature (c) 0 0.4 1.4 1.2 1 0.8 0.6 0.2 0 25 50 75 100 150 power dissipation (w) 125 85 jedec jesd51-7 high effective thermal conductivity test board 0.1 1.250w qsop16 ja =112c/w 909mw 893mw 435mw so8 ja =110c/w sot23-6 ja =230c/w so16 (0.150?) ja =80c/w figure 14. a v = +2 - + 325 ? 325 ? in- in+ el5106, el5306
8 supply voltage range and single-supply operation the el5106 and el5306 have been designed to operate with supply voltages having a span of greater than or equal to 5v and less than 11v. in practical terms, this means that the el5106 and el5306 will operate on dual supplies ranging from 2.5v to 5v. with single-supply, the el5106 and el5306 will operate from 5v to 10v. as supply voltages continue to decrease, it becomes necessary to provide input and output voltage ranges that can get as close as possible to the supply voltages. the el5106 and el5306 have an input range which extends to within 2v of either supply. so , for example, on 5v supplies, the el5106 and el5306 have an input range which spans 3v. the output range is also qu ite large, extending to within 1v of the supply rail. on a 5v supply, the output is therefore capable of swinging from -4v to +4v. single-supply output range is larger because of t he increased negative swing due to the external pull-down resistor to ground. figure 16 shows an ac-coupled, gain of +2, +5v single supply circuit configuration. video performance for good video performance, an amplifier is required to maintain the same output impedance and the same frequency response as dc levels are changed at the output. this is especially difficult when driving a standard video load of 150 ? , because of the change in output current with dc level. previously, good differential gain could only be achieved by running high idle currents through the output transistors (to reduce variat ions in output impedance). special circuitries have been incorporated in the el5106 and el5306 to reduce the variatio n of output impedance with current output. this results in dg and dp specifications of 0.02% and 0.04, while driving 150 ? at a gain of 2. output drive capability in spite of its low 1.5ma of supply current per amplifier, the el5106 and el5306 are capable of providing a maximum of 125ma of output current. driving cables and capacitive loads when used as a cable driver, double termination is always recommended for reflection-free performance. for those applications, the back-termination series resistor will decouple the el5106 and el5306 from the cable and allow extensive capacitive drive. however, other applications may have high capacitive loads without a back-termination resistor. in these applications, a small series resistor (usually between 5 ? and 50 ? ) can be placed in series with the output to eliminate most peaking. figure 15. a v = -1 - + 325 ? 325 ? in- in+ figure 16. a v = +1 - + 325 ? 325 ? in- in+ figure 17. - + 325 ? 325 ? v in +5 0.1f 1k 1k 0.1f +5 v out el5106, el5306
9 current limiting the el5106 and el5306 have no internal current-limiting circuitry. if the output is short ed, it is possible to exceed the absolute maximum rating for output current or power dissipation, potentially resultin g in the destruction of the device. power dissipation with the high output drive capability of the el5106 and el5306, it is possible to exceed the 125c absolute maximum junction temperature under certain very high load current conditions. generally speaking when r l falls below about 25 ? , it is important to calc ulate the maximum junction temperature (t jmax ) for the application to determine if power supply voltages, load conditions, or package type need to be modified for the el5106 and el5306 to remain in the safe operating area. these parameters are calculated as follows: where: t max = maximum ambient temperature ja = thermal resistance of the package n = number of amplifiers in the package pd max = maximum power dissipation of each amplifier in the package pd max for each amplifier can be calculated as follows: where: v s = supply voltage i smax = maximum bias supply current v outmax = maximum output voltage (required) r l = load resistance so package outline drawing t jmax t max ja npd max () + = pd max 2 ( v s i smax ) v s ( - v outmax ) v outmax r l ---------------------------- + = el5106, el5306
