ADI LTC1052CN8

Общее назначение

Overview

The LTC1052CN8 and LTC7652 are low noise zero-drift op amps manufactured using an enhanced LTCMOS™ silicon gate process. Chopper-stabilization constantly corrects offset voltage errors. Both initial offset and changes in the offset due to time, temperature and common mode voltage are corrected. This, coupled with picoampere input currents, gives these amplifiers unmatched performance.

The chopper circuitry is entirely internal and completely transparent to the user. Only two external capacitors are required to alternately sample-and-hold the offset correction voltage and the amplified input signal. Control circuitry is brought out on the 14-pin and 16-pin versions to allow the sampling of the LTC1052CN8 to be synchronized with an external frequency source.
