Microchip zero-drift op amp is low power for medical
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.
- 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 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.
