Micropower dual op-amp for battery and sensor conditioning
The STMicroelectronics TSV612AIST is a dual CMOS operational amplifier designed for low-power, single-supply applications. Gain bandwidth product is 120 kHz, and the slew rate is 0.04 V/µs — numbers that tell you this is a micropart for DC-accurate or low-frequency signal conditioning, not for driving fast edges.
At the low end, the rail-to-rail output lets you use nearly the full supply swing for the signal path — useful when the ADC reference is the same battery.
