TS1872A - STMicroelectronics

TS1872A low power operational amplifiers

The TS187x (single, dual and quad) device can operate with voltages as low as 1.8 V. They feature both input and output rail-to-rail. The common mode input voltage extends 200 mV beyond the supply voltages at 25 °C, while the output voltage swing is within 100 mV of each rail with a 600 Ω load resistor. The devices consume typically 400 µA per channel while .
