lt2178/lt2179 1 21789fc typical application description 17a max, dual and quad, single supply, precision op amps the lt ? 2178 is a micropower dual op amp in a surface mount standard 8-pin con? guration, the lt2179 is a micropower quad op amp offered in a surface mount 14-pin package. both devices are optimized for single supply operation at 5v. speci? cations are also provided at 15v supply. the extremely low supply current is combined with true precision speci? cations: offset voltage is 30v and offset current is 50pa. both offset parameters have low drift with temperature. the 1.5pa p-p current noise and picoampere offset current permit the use the megohm level source resistors without introducing serious errors. voltage noise, at 0.9v p-p , is remarkably low considering the low supply current. the lt2178/lt2179 can be operated from a single supply (as low as one lithium-cell or two nicd batteries). the input range goes below ground. the all-npn output stage swings to within a few millivolts of ground while sinking current. no power consuming pull down resistors are needed. for surface mount applications where three times higher supply current is acceptable, the micropower lt1077 single, lt2078 dual and lt2079 quad are recommended. the lt1077/lt2078/lt2079 have signi? cantly higher bandwidth, slew rate, lower voltage noise and better output drive capability. for applications requiring dip packages refer to the lt1178/lt1179. self-buffered, dual output, micropower reference features applications n so package with standard pinout n supply current per ampli? er: 17a max n offset voltage: 70v max n offset current: 250pa max n input bias current: 5na max n voltage noise: 0.9v p-p , 0.1hz to 10hz n current noise: 1.5pa p-p , 0.1hz to 10hz n offset voltage drift: 0.5v/c n gain bandwidth product: 85khz n slew rate: 0.04v/s n single supply operation input voltage range includes ground output swings to ground while sinking current no pull-down resistors needed n output sources and sinks 5ma load current n battery- or solar-powered systems portable instrumentation remote sensor ampli? er satellite circuitry n micropower sample-and-hold n thermocouple ampli? er n micropower filters supply current vs temperature C + 2 3 + C 5 6 1/2 lt2178 1 0.1f 250k 1m* 1m* lt1004-1.2 4 7 2m 0.1f 1.2365v output 1/2 lt2178 2.470v output 4v to 9v 21789 ta01 total battery current = 28ma output accuracy = p 0.4% max temperature coefficient = 20ppm/c load regulation = 25ppm/ma, i l 5ma, v + 5v line regulation = 10ppm/v * 0.1% film resistors 8 temperature (c) C50 supply current per amplifier a) C25 0 25 50 21789 ta02 75 20 18 16 14 12 10 100 v s = p 15v v s = 5v, 0v v s = p 1.5v l , lt, ltc, ltm, linear technology and the linear logo are registered trademarks of linear technology corporation. all other trademarks are the property of their respective owners.
