Description
The Microchip Technology Inc. MCP6401/1R/1U/2/4
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 single supply voltage as
low as 1.8V. These features make the family of op
amps well suited for single-supply, battery-powered
applications.
The MCP6401/1R/1U/2/4 family is designed with
Microchip’s advanced CMOS process and offered in
single packages. All devices are available in the
extended temperature range, with a power supply
range of 1.8V to 6.0V.
