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.
