3. FAN4174 Ultra-Low Cost, Rail-to-Rail I/O, CMOS Amplifier
Features
200µA 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
Package 5 Lead SC-70
FAN4174 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 2.5Vto 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.
