The LTC1052 and LTC7652 are low noise zero-drift op amps manufactured using Linear Technology's enhanced LTCMOS silicon gate process
The handbook describes the LTC1052 and LTC7652 low‑noise zero‑drift operational amplifiers, highlighting their chopper‑stabilized architecture, ultra‑low offset, and picoampere input currents. It lists key features such as a guaranteed maximum offset of 5 µV, single‑supply operation from 4.75 V to 16 V, and high gain, CMRR, and PSRR values.
Detailed electrical characteristics, typical performance curves, and theory of operation are provided, along with guidance on external capacitor selection, achieving picoampere/microvolt performance, and package dimensions for both PDIP and SOIC variants. The document serves as a reference for designers integrating these amplifiers into thermocouple, strain‑gauge, and medical instrumentation applications.
