The single-amplifier THS4021 and the dual-amplifier THS4022 offer very good ac performance with 350-MHz bandwidth, 470-V/µs slew rate, and 40-ns settling time (0.1%). The THS4021 and THS4022 are stable at gains of 10 (-9) or greater. These amplifiers have a high drive capability of 100 mA and draw only 7.8-mA supply current per channel. With total harmonic distortion (THD) of -68 dBc at f = 1 MHz, the THS4021 and THS4022 are ideally suited for applications requiring low distortion. |
