ƒ 3.7MHz Bandwidth
ƒ Output Swing to within 10mV of Either Rail
ƒ Input Voltage Range Exceeds the Rails
ƒ 3V/µs Slew Rate
ƒ 25nV/Hz Input Voltage Noise
ƒ FAN4931 Competes with LMV931; Available in

ƒ Fully Specified at +2.7V and +5V Supplies
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.
Applications
ƒ Portable / Battery-Powered Applications
ƒ PCMCIA, USB
ƒ Mobile Communications, Cellular Phones, Pagers
ƒ Notebooks and PDAs
ƒ Sensor Interface
ƒ A/D Buffer
ƒ Active Filters
ƒ Signal Conditioning
ƒ Portable Test Instruments
