FAN4931: Ultra-Low Cost, Rail to Rail I/O, CMOS Amplifier

FAN4931 is an ultra-low cost voltage feedback amplifier with CMOS inputs that consumes only 200 µA of supply current, while providing ±33 mA of output short-circuit current. This amplifier is designed to operate from 2.5 V to 5 V supplies. The common-mode voltage range extends beyond the negative and positive rails. The FAN4931 is designed on a CMOS process and provides 3.7 MHz of bandwidth and 3 V / μs of slew rate at a supply voltage of 5 V. This amplifier operates and is reliable over a wide temperature range -40°C to +125°C. The combination of extended temperature operation, low power, rail-to-rail performance, low voltage operation,and tiny package optimizes this amplifier for use in many industrial, general purpose and battery powered applications.
