LT1678IS8#PBF

LT1678 is a dual channel, low noise, rail-to-rail, precision op-amp. This device bring precision as well as low noise to single supply applications as low as 3V. The input range exceeds the power supply by 100mV with no phase inversion while the output can swing to within 170mV of either rail. It is widely used in application such as strain gauge amplifiers, portable microphones, battery-powered rail-to-rail instrumentation, low noise signal processing, microvolt accuracy threshold detection, infrared detectors etc.
