Ultra-Low Cost, Rail to Rail I/O, CMOS Amplifier

General Description

FAN4931 is an ultra-low cost voltage feedback amplifier with CMOS inputs that consumes only 200µA of supply current, while providing ±33mA of output short-circuit current. This amplifier is designed to operate from 2.5V to 5V supplies. The common-mode voltage range extends beyond the negative and positive rails.     The FAN4931 is designed on a CMOS process and provides 3.7MHz of bandwidth and 3V/µs of slew rate at a supply voltage of 5V. The combination of low power, rail-to-rail performance, low-voltage operation, and tiny package options make this amplifier well suited for use in general-purpose and battery-powered applications.
