说明

The THS4081 and THS4082 are ultralow-power, high-speed voltage feedback amplifiers that are ideal for communication and video applications. These amplifiers operate off of a very low 3.4-mA quiescent current per channel and have a high output drive capability of 85 mA. The signal-amplifier THS4081 and the dual-amplifier THS4082 offer very good ac performance with 175-MHz bandwidth, 230-V/us slew rate, and 43-ns settling time (0.1%). With total harmonic distortion (THD) of x9664 dBc at f = 1 MHz, the THS4081 and THS4082 are ideally suited for applications requiring low distortion.
