GENERAL DESCRIPTION
The TC901 is a monolithic, auto-zeroed operational amplifier. It is a second-generation design of the TC91X CMOS chopper-stabilized op amps with on-chip capacitors.
Elimination of the external capacitors allows the designer to increase reliability, lower cost, and simplify design by lowering parts count.
Since the TC901 is an auto-zeroing op amp, input offset voltage is very low. More important, there is almost zero drift with time. This eliminates production line adjustments, as well as periodic calibration.
