The Microchip Technology Inc. MCP6401/1R/1U family of operational amplifiers (op amps) has low quiescent current (45 µA, 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). The MCP6401/1R/1U family is designed with Microchip’s advanced CMOS process. It is offered in SC70 and SOT23 packages for -40°C to +125°C temperature range and in SOT23 for -40°C to +150°C temperature range with a power supply range of 1.8V to 6.0V. These features make the family of op amps well suited for single-supply, battery-powered, automotive and industrial applications.
