MCP6071/2/4
Description
The Microchip Technology Inc. MCP6071/2/4 family of
operational amplifiers (op amps) has low input offset
voltage (
output operation. This family is unity gain stable and
has a gain bandwidth product of 1.2 MHz (typical).
These devices operate with a single supply voltage as
low as 1.8V, while drawing low quiescent current per
amplifier (110 µA, typical). These features make the
family of op amps well suited for single-supply, high
precision, battery-powered applicaitons.
The
(MCP6071), dual (MCP6072), and quad (MCP6074)
configurations.
The MCP6071/2/4 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.
