MCP6422

The Microchip’s MCP6421/2/4 operational amplifiers (op amps) has low input bias current (1 pA, typical) and rail-to-rail input and output operation. This family is unity gain stable and has a gain bandwidth product of 90 kHz (typical). These devices operate with a single-supply voltage as low as 1.8V, while only drawing 4.4 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 MCP6422 family is offered in SOIC and MSOP packages. All devices are designed using an advanced CMOS process and fully specified in extended temperature range from -40°C to +125°C.
