Description
The Microchip Technology Inc. MCP6051/2/4 family of operational amplifiers (op amps) has low input offset
voltage (±150 µV, maximum) and rail-to-rail input and
output operation. This family is unity gain stable and has a gain bandwidth product of 385 kHz (typical). These devices operate with a single supply voltage as low as 1.8V, while drawing low quiescent current per amplifier (30 µA, typical). These features make the family of op amps well suited for single-supply, high precision, battery-powered applications.
The MCP6051/2/4 family is offered in single (MCP6051), dual (MCP6052), and quad (MCP6054) configurations.
The MCP6051/2/4 is designed with Microchip’s advanced CMOS process. All devices are available in the extended temperature range, with a power supply range of 1.8V to 6.0V.
