DESCRIPTION
The THS4222 family is a set of rail-to-rail output single,
dual, and triple 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/
s slew
rate and harmonic distortion (THD) at –90 dBc at 5 MHz.
