General Description
The FAN4272 is an ultra-low cost, low power, voltage
feedback amplifier. At 5V, the FAN4272 uses only
160
μ
A of supply current per amplifier and is
designed to operate from a supply range of 2.5V to
5.5V (±1.25V to 2.75V). The input voltage range
exceeds the negative and positive rails.
The FAN4272 offers high bipolar performance at a low
CMOS price. The FAN4272 offers superior dynamic
performance with a 4.9MHz small signal bandwidth
and 5.3V/
μ
s slew rate. The combination of low
power, high bandwidth, and rail-to-rail performance
make the FAN4272 well suited for battery-powered
communication/computing systems.
