DESCRIPTION
The THS4222 family is a set of rail-to-rail output single, and dual low-voltage, high-output swing, low-distortion high-speed
amplifiers ideal for driving data converters, video switching or low distortion applications.This family of voltage feedback
amplifiers can operate from a single 15-V power supply down to a single 3-V power supply while consuming only 14 mA of
quiescent current per channel. In addition, the family offers excellent ac performance with 230-MHz bandwidth, 975-V/µs
slew rate and harmonic distortion (THD) at –90 dBc at 5 MHz.
