Battery Current Sensing
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.
