The Microchip Technology Inc. MCP6401/1R/1U family of operational amplifiers (op amps) has low quiescent current (45 A, typical) and rail-to-rail input and output operation. This family is unity gain stable and has a gain bandwidth product of 1 MHz (typical). These devices operate with a single supply voltage as low as 1.8V. These features make the family of op amps well suited for single-supply, battery-powered applications.
