Microchip - MCP6V06: 7, 8 Data Sheet Op Amps with 300 µA Auto-Zero Current, 7 and 8 Pin Configurations Manual and User Guide

Summary

The MCP6V06/7/8 are a family of high-precision, auto-zeroed operational amplifiers optimized for low power consumption across diverse voltage ranges. These differential op amps provide excellent noise rejection (PSRR/CMRR) and rail-to-rail I/O. The manual provides detailed electrical specifications, performance data across extreme temperatures, application notes, and design aids. They are engineered for critical applications including medical instrumentation, sensor conditioning, temperature measurement, and portable data acquisition systems requiring high DC accuracy.

MCP6V06/7/8 µA, Auto-Zeroed Op Amps

Features Description High DC Precision: The Microchip Technology Inc. MCP6V06/7/8 family of

VOS Drift: ±50 n V/°C (maximum) operational amplifiers has input offset voltage correction for very low offset and offset drift. These

VOS: ±3 µV (maximum)

devices have a wide gain bandwidth product (1.3 MHz,

AOL: 125 d B (minimum)

typical) and strongly reject switching noise. They are

PSRR: 125 d B (minimum)

unity gain stable, have no 1/f noise, and have good

CMRR: 120 d B (minimum) PSRR and CMRR. These products operate with a

Eni: 1.7 µVP-P (typical), f 0.1 Hz to 10 Hz single supply voltage as low as 1.8V, while drawing µA/amplifier (typical) of quiescent current.

Eni: 0.54 µVp-p (typical), f 0.01 Hz to 1 Hz

Low Power and Supply Voltages: The Microchip Technology Inc. MCP6V06/7/8 op amps are offered in single (MCP6V06), single with Chip

IQ: 300 µA/amplifier (typical)

Select (CS) (MCP6V08), and dual (MCP6V07). They

Wide Supply Voltage Range: 1.8V to 5.5V

are designed in an advanced CMOS process.
