op-amp
■ Tested on 5V power supply
■ Data min. and max. are tested during
production
Description
The TSH340 is a single supply video buffer
featuring an internal gain of 6dB and a large
bandwidth of 320MHz for only 9.8mA of quiescent
current.
An advantage of this circuit is its input and output
negative rail feature, which is very close to GND in
single supply. This rail is tested and guaranteed
during production at 60mV maximum from GND
on a 150Ω load. This allows a good output swing
which fits perfectly when driving a video signal on
a 75Ω video line. Chapter 5 of this datasheet
gives technical support when using the TSH340
as a driver for video DAC output on a video line. In
particular, this chapter focuses on applying a
video signal DC shift to avoid any clamping of the
synchronization tip.
The TSH340 is available in tiny SOT23-5 and
SO8 plastic packages.
