Description:

The MCP6441 device is a single nanopower

operational amplifier (op amp), which has low

quiescent current (450 nA, typical) and rail-to-rail input

and output operation. This op amp is unity gain stable

and has a gain bandwidth product of 9 kHz (typical).

These devices operate with a single supply voltage as

low as 1.4V. These features make the family of op

amps well suited for single-supply, battery-powered

applications.

The MCP6441 op amp is designed with Microchip’s

advanced CMOS process and offered in the 5-pin

SC70 and SOT-23 single packages. All devices are

available in the extended temperature range, with a

power supply range of 1.4V to 6.0V.
