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.

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)
