Detailed Description
This family is unity gain stable and has a gain bandwidth product of 7.5 MHz (typical). These devices operate with a single-supply voltage as low as 2.4V, while only drawing 530 µA/amplifier (typical) of quiescent current. These features make the family of op amps well suited for photodiode amplifier, pH electrode amplifier, low leakage amplifier, and battery powered signal conditioning applications, etc. The MCP6491 family is offered in SOT23 and SC70 packages. All devices are designed using an advanced CMOS process and fully specified in extended temperature range from -40°C to +125°C.
