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.
