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-ampli-

fier 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.
