Microchip zero-drift op amp is low power for medical

Description

The MCP6V11/1U family of operatioinal amplifiers provides input offset voltage correction for very low offset and offset drift. These are low power devices, with a gain bandwidth product of 80 kHz. They are unity gain stable, have no 1/f noise, and provide superior CMRR and PSRR performance. These products operate with a single supply voltage as low as 1.6V with a quiescent current of only 7.5 uA.

Features

    • Zero Drift architecture
    • Maximum offset of only 8 uV
    • Maximum offset drift of 50 nV/C
    • No 1/f noise
    • Low Power operation
    • Small SC-70 and SOT-23 packaging

Microchip zero-drift op amp is low power for medical

Microchip has introduced zero-drift operational amplifiers which can operate with a single supply voltage as low as 1.6V and a quiescent current as low as 7.5µA.

For low power medical diagnostic systems the MCP6V11/31 op amps are designed on a self-correcting architecture which provides a maximum input offset voltage of 8µV for low-offset and low-offset drift, enabling maximum accuracy across time and temperature.

The MCP6V11 offers 80kHz of gain bandwidth product, with a low typical quiescent current of only 7.5µA.

The MCP6V31 provides 300kHz of gain bandwidth product, coupled with a low typical quiescent current of 23µA.

These single amplifiers are available in small 5-pin SOT-23 and 5-pin SC-70 packages.
