Microchip, MCP6V19-E/ST

The MCP6V16/7/9 family of operational amplifiers provides input offset voltage correction for very low offset and offset drift. These are low power devices, with a gain bandwidth product of 80 kHz. They are unity gain stable, have no 1/f noise, and provide superior CMRR and PSRR performance. These products operate with a single supply voltage as low as 1.6V with a maximum quiescent current of only 11 μW.

Zero-Drift architecture
Maximum offset of only 25 uV
Maximum offset drift of 150 nV/C
No 1/f noise
Power consumption as low as 10.4 uW per channel
