MCP6V31/1U

23 µA, 300 kHz Zero-Drift Op Amps

Features

Description

• High DC Precision:

The Microchip Technology Inc. MCP6V31/1U family of

operational amplifiers provides input offset voltage

correction for very low offset and offset drift. These are

low power devices, with a gain bandwidth product of

300 kHz (typical). They are unity gain stable, have no

1/f noise, and have good Power Supply Rejection Ratio

(PSRR) and Common Mode Rejection Ratio (CMRR).

These products operate with a single supply voltage as

low as 1.8V, while drawing 23 µA/amplifier (typical) of

quiescent current.

- V_OSDrift: ±50 nV/°C (maximum)

- V_OS: ±8 µV (maximum)

- A_OL: 120 dB (minimum, V_DD= 5.5V)

- PSRR: 120 dB (minimum, V_DD= 5.5V)

- CMRR: 120 dB (minimum, V_DD= 5.5V)

- E_ni: 1.0 µV_P-P(typical), f = 0.1 Hz to 10 Hz

- E_ni: 0.33 µV_P-P(typical), f = 0.01 Hz to 1 Hz

• Low Power and Supply Voltages:

- I_Q: 23 µA/amplifier (typical)

The Microchip Technology Inc. MCP6V31/1U op amps

are offered in single (MCP6V31 and MCP6V31U)

packages. They were designed using an advanced

CMOS process.

- Wide Supply Voltage Range: 1.8V to 5.5V

• Small Packages

- Singles in SC70, SOT-23

• Easy to Use:
