175 - MHz的低功耗高速放大器 175-MHz LOW-POWER HIGH-SPEED AMPLIFIERS
description
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/µs slew rate, and 43-ns settling time 0.1%. With total harmonic distortion THD of −64 dBc at f = 1 MHz, the THS4081 and THS4082 are ideally suited for applications requiring low distortion.
