TSH340 Video buffer, single supply, low input and output rail of 40mV/GND

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 150Ωload. This allows a good output swing which fits perfectly when driving a video signal on a 75Ω video line. Chapter 5of 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
