General Description

1 GHz, 800 V/µs, Vn = 7 nV/√Hz 1.4 GHz, 900 V/µs, Vn = 3 nV/√Hz 250 MHz, 150 V/µs, Vn = 6.5 nV/√Hz 500 MHz, 1800 V/µs, Vn = 5.5 nV/√Hz 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.
