description
The THS4041 and THS4042 are single/dual,
high-speed voltage feedback amplifiers capable
of driving any capacitive load. This makes them
ideal for a wide range of applications including
driving video lines or buffering ADCs. The devices
feature high 165-MHz bandwidth and 400-V/µsec
slew rate. The THS4041/2 are stable at all gains
for both inverting and noninverting configurations.
For video applications, the THS4041/2 offer
excellent video performance with 0.01% differential gain error and 0.01° differential phase error.
These amplifiers can drive up to 100 mA into a
20-Ω load and operate off power supplies ranging
from ±5V to ±15V.
