Description
The FAN4113 is a low cost, voltage feedback amplifier that
consumes only 640µA of supply current. The FAN4113 is
designed to operate from +1.2V to 5.5V or ±0.6V to ±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.
