Microchip Technology
General Description
The TC911 CMOS auto-zeroed operational amplifier is the first complete monolithic chopper stabilized amplifier. Chopper operational amplifiers like the ICL7650/7652 and LTC1052 require user supplied, external offset compensation storage capacitors. External capacitors are not required with the TC911. Just as easy to use as the conventional OP07 type amplifier, the TC911 significantly reduces offset voltage errors. Pinout matches the OP07/741/7650 8-pin mini-DIP configuration.
