General Description

The LTC1052 is a low-noise chopper-stabilized operational amplifier manufactured using CMOS silicon-gate technology.

The device is well-suited for applications such as thermocouple amplifiers, strain-gauge amplifiers, low-level signal processing, and medical instrumentation.

Chopper stabilization constantly corrects input offset voltage errors, including both errors in the initial input offset voltage and errors in input offset voltage due to time, temperature, and mon-mode input voltage.
