THS4042 Voltage-Feedback Amplifier

Texas Instruments' THS4042 is a dual, high-speed, voltage-feedback amplifier 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 THS4042 is stable at all gains for both inverting and noninverting configurations. For video applications, the THS4042 offers 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 ±5 to ±15 V.
