The THS4041 is a single, high-speed voltage feedback amplifier capable of driving any capacitive load. This makes it ideal for a wide range of applications including driving video lines or buffering ADCs. The device features high 165-MHz bandwidth and 400-V/μs slew rate. The THS4041 is stable at all gains for both inverting and noninverting configurations. For video applications, the THS4041 offers excellent video performance with 0.01% differential gain error and 0.01° differential phase error. This amplifier can drive up to 100 mA into a 20- load and operate off power supplies ranging from ±5 V to ±15 V.
