TC7652 - Low Noise/ Chopper Stabilized Operational Amplifier

General Description

The TC7652 is a lower noise version of the TC7650, sacrificing some input specifications (bias current and bandwidth) to achieve a 10x reduction in noise.

Key Features

  • Low Offset Over Temperature Range: 10µV Ultra Low Long Term Drift: 150nV/Month Low Temperature Drift: 100nV/°C Low DC Input Bias Current: 15pA High Gain, CMRR and PSRR: 110dB Min Low Input Noise Voltage: 0.2µVp-p (DC to 1Hz) Internally Compensated for Unity Gain Operation Clamp Circuit for Fast Overload Recovery General.
