Description
The FAN4272 is an ultra-low cost, low power, voltage feed-
back amplifier. At 5V, the FAN4272 uses only 160 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 4MHz small signal bandwidth and 4V/ 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.
