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

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.
