Description
The TSH341 is a single supply operational
amplifier featuring a large bandwidth of 300MHz
at unity gain for only 9.8mA of quiescent current.
An advantage of this circuit is its low input and
output rail feature which is very close to GND in
single supply. This rail is tested and guaranteed
during production at 60mV (max.) 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 gives technical support
when using the TSH341 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 TSH341 is available in the tiny SOT23-5 and
SO8 plastic packages.
