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.
