Description

The FAN4113 is a low cost, voltage feedback amplifier that

consumes only 640

µA of supply current. The FAN4113 is

designed to operate from +1.2V to 5.5V (±2.75V) supplies.

The common mode voltage range extends below the negative

rail and the output provides rail-to-rail performance.

The FAN4113 is designed on a complementary bipolar

process and provides 36MHz of bandwidth and 8V/

µs of slew

rate at a low supply voltage of 1.2V. The combination of low

power, rail-to-rail performance, low voltage operation, and

tiny package options make the FAN4113 well suited for use

in personal electronics equipment such as cellular handsets,

pagers, PDAs, and other battery powered applications.
