FAN4931

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

Features

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.

200µA Supply Current per Amplifier

3.7MHz Bandwidth

Output Swing to within 10mV of Either Rail

Input Voltage Range Exceeds the Rails

3V/µs Slew Rate

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.
