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 85ĂmA. 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.
