The THS4051 and THS4052 are general-purpose, single/dual, high-speed voltage feedback amplifiers ideal for a wide range of applications including video, communication, and imaging. The devices offer very good ac performance with 70-MHz bandwidth, 240-V/us slew rate, and 60-ns settling time (0.1%). The THS4051/2 are stable at all gains for both inverting and non-inverting configurations. These amplifiers have a high output drive capability of 100 mA and draw only 8.5-mA supply current per channel. Excellent professional video results can be obtained with the low differential gain/phase errors of 0.01%/0.01° and wide 0.1 dB flatness to 30 MHz. For applications requiring low distortion, the THS4051/2 is ideally suited with total harmonic distortion of -82 dBc at 1 MHz.
