Description
The Microchip Technology Inc. MCP6031/2/3/4 family of operational amplifiers (op amps) operate with a single supply voltage as low as 1.8V, while drawing ultra low quiescent current per amplifier (0.9 uA, typical). This family also has low input offset voltage ( 150 uV, 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 specs make these op amps appropriate for low frequency applications, such as battery current monitoring and sensor conditioning. The MCP6031/2/3/4 family is offered in single (MCP6031), single with power saving Chip Select (CS) input (MCP6033), dual (MCP6032), and quad (MCP6034) configurations. The MCP6031/2/3/4 family 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 5.5V.
