Description
The Microchip Technology Inc. MCP6031/2/3/4 family of operational amplifiers (op amps) operates with a single-supply voltage as low as 1.8V, while drawing ultra-low quiescent current per amplifier (0.9 µA, typical). This family also has low input offset voltage
(150 µV, maximum) and rail-to-rail input and output
operation. This combination of features supports battery-powered and portable applications.
The MCP6031/2/3/4 family is unity gain stable and has a gain bandwidth product of 10 kHz (typical). These specifications make these op amps appropriate for low-frequency applications, su...
