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.

1)All voltage values, except differential voltage are with respect to network terminal.

2)Differential voltage are non-inverting input terminal with respect to the inverting input terminal.

3)The magnitude of input and output voltage must never exceed VCC +0.3V.

4)An output current limitation protects the circuit from transient currents. Short-circuits can cause excessive heating. Destructive dissipation can result from short circuit on amplifiers.
