1 / 10 page REV. 1D December 2004 www.fairchildsemi.com Features at +5V • 200 µA supply current per amplifier • 3.7MHz bandwidth • Output swing to within 10mV of either rail • Input voltage range exceeds the rails • 3V/ µs slew rate • 25nV/ √Hz input voltage noise • Competes with OPA340 and TLV2461 •Package options (SC70-5 and SOT23-5) • Fully specified at +2.7V and +5V supplies Applications • Portable/battery-powered applications • PCMCIA, USB • Mobile communications, cellular phones, pagers • Notebooks and PDA’s • Sensor interface • A/D buffer • Active filters • Signal conditioning • Portable test instruments Description The FAN4174 is a single, ultra-low cost, voltage feedback amplifier with CMOS inputs that consumes only 200 µA of supply current while providing ±33mA of output short circuit current. The FAN4174 is designed to operate from 2.5V to 5V supplies. The common mode voltage range extends beyond the negative and positive rails. The FAN4174 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 the FAN4174 well suited for use in many gen- eral purpose and battery powered applications.
