By reducing the digital calibration circuit operating frequency to 120MHz, low-power operation is also achieved, with 37mW power consumption (analog:19mW, digital:18mW).

The MCP65X 50-MHz rail-to-rail operational amplifiers from Microchip Technology include an on-chip “mCal” calibration circuit that calibrates offset voltage at powerup or on-command ...
