The AD8613AKSZ-REEL7 / AD8617 / AD8619 are single, dual, and quad micropower,rail-to-rail input and output amplifiers that feature lowsupply current, as well as low input voltage and current noise.The parts are fully specified to operate from 1.8 V to 5 V singlesupply, or ±0.9 V and ±2.5 V dual supply. The combination of lownoise, very low input bias currents, and low power consumptionmake the AD8613AKSZ-REEL7 / AD8617 / AD8619 especially useful in portableand loop-powered instrumentation.
The ability to swing rail-to-rail at both the input and outputenables designers to buffer CMOS ADCs, DACs, ASICs, andother wide output swing devices in low power, single-supplysystems.
The AD8613AKSZ-REEL7 is available in a 5-lead SC70 package and a 5-leadTSOT-23 package. The AD8617 is available in 8-lead MSOP,8-lead SOIC, and 8-lead LFCSP packages. The AD8619 isavailable in 14-lead TSSOP and 14-lead SOIC packages. TheAD8617W is qualified for automotive applications and isavailable in 8-lead MSOP and 8-lead SOIC packages. TheAD8619W is qualified for automotive applications and isavailable in 14-lead SOIC and 14-lead TSSOP packages.
