Microchip, MCP6V36T-E/OT

The MCP6V36/7/9 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 300 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 1.8V with a maximum quiescent current of only 34 uA.

Zero-Drift architecture
Maximum offset of only 25 uV
Maximum offset drift of only 150 nV/C
No 1/f noise
Less than 42 uW of power consumption with 300 kHz bandwidth
Small SC70 and SOT-23 packaging
