FAN4272

www.fairchildsemi.com FAN4272 Dual, Low Cost, +2.7V & +5V, Rail-to-Rail I/O Amplifier Features at 2.7V 130µA supply current per amplifier 4MHz bandwidth Output swings to within 25mV of either rail Input voltage range exceeds the rail by >250mV 4V/µs slew rate 16mA output current 22nV/√Hz input voltage noise Operating temperature range: -40°C to +125°C Directly replaces TLC2272 in single supply applications Available in SOIC-8 and MSOP-8 package options Available evaluation boards: KEB006 (SOIC) and KEB010 (MSOP) Description The FAN4272 is an ultra-low cost, low power, voltage feedback amplifier. At 5V, the FAN4272 uses only 160µA of supply current per amplifier and is designed to operate from a supply range of 2.5V to 5.5V (±1.25V to 2.75V). The input voltage range exceeds the negative and positive rails. The FAN4272 offers high bipolar performance at a low CMOS price. The FAN4272 offers superior dynamic performance with a 4MHz small signal bandwidth and 4V/µs slew rate. The combination of low power, high bandwidth, and rail-torail performance make the FAN4272 well suited for batterypowered communication/computing systems. Large Signal Freq.
