Description
The
Microchip
Technology
Inc.
MCP6401/1R/1U/2/4/6/7/9 family of operational
amplifiers (op amps) has low quiescent current
(45 µA, typical) and rail-to-rail input and output
operation. This family is unity gain stable and has a
gain bandwidth product of 1 MHz (typical). These
devices operate with a power supply voltage of 1.8V to
6.0V. These features make the family of op amps well
suited for single-supply, battery-powered applications.
The MCP6401/1R/1U/2/4/6/7/9 family is designed with
Microchip’s advanced CMOS process and offered in
single, dual and quad packages. The devices are
available in two extended temperature ranges (E temp
and H temp) with different package types, which
makes them well-suited for automotive and industrial
applications.
