FAN4113

www.fairchildsemi.com FAN4113 1.2V, 36MHz, Low Power Rail-to-Rail Amplifier Features at +1.2V 640µA supply current per amplifier 36MHz gain bandwidth product Output voltage range: 0.06V to 1.10V Input voltage range: -0.4V to +0.2V 8V/µs slew rate 12nV/√Hz input voltage noise Package option (SC70-5) Fully specified at +1.2V, +2.7V, and +5V supplies 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 (±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.
