Description
The TSH7x series offers single, dual, triple, and
quad operational amplifiers featuring high video
performances with large bandwidth, low
distortion, and excellent supply voltage rejection.
Running with a single supply voltage from 3 V to
12 V, these amplifiers feature a large output
voltage swing and high output current capable of
driving standard 150
Ω
loads. A low operating
voltage makes TSH7x amplifiers ideal for use in
portable equipment. The TSH71, TSH73, and
TSH75 also feature standby inputs, each of which
allows the op-amp to be put into a standby mode
with low-power consumption and high-output
impedance. This function allows power saving or
signal switching/multiplexing for high-speed
applications and video applications. To
economize both board space and weight, the
TSH7x series is proposed in SOT23-5, SO, and
TSSOP packages.

Typical application: video driver
A typical application for the TSH7x family is that of a video driver for driving STi7xxx DAC
outputs on 75-ohm lines.
