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.
