The MCP6401T-E/LT is an Operational Amplifier has low quiescent current (45μA, typical) and rail-to-rail input and output operation. This family is unity gain stable and has a gain bandwidth product of 1MHz (typical). The device operates with a power supply voltage of 1.8 to 6.0V. These features make the family of op amps well suited for single-supply, battery-powered applications.
