MCP6441/2/4
Description:
The MCP6441/2/4 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 MCP6441/2/4 op amp is designed with Microchip’s
advanced CMOS process and offered in single
(MCP6441), dual (MCP6442), and quad (MCP6444)
configurations. All devices are available in the
extended temperature range, with a power supply
range of 1.4V to 6.0V.
