TC7652 Datasheet Low Noise/ Chopper Stabilized Operational Amplifier

Manufacturer: Microchip Technology

Overview: 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.

All the other benefits of the chopper technique are present, (i.e, freedom from offset adjust, drift and reliability problems from external trim ponents).

Like the TC7650, the TC7652 requires only two noncritical external caps for storing the chopped null potentials.

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.
