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 µA,
typical). This family also has low input offset voltage
(±150 µV, 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 fre-
quency 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 Micro-
chip’s advanced CMOS process. All devices are
available in the extended temperature range, with a
power supply range of 1.8V to 5.5V.
