15.14 TSH343
15.14.1
The TSH343 is a triple single-supply video buffer featuring an internal gain of 6dB and a
large bandwidth of 280MHz. The main advantage of this circuit is that its input DC level
shifter allows for video signals on 75
synchronization tip of the video signal, while using a single 5V power supply with no
input capacitor. The DC level shifter is internally fixed and optimized to keep the output
video signals between low and high output rails in the best position for the greatest
linearity. Chapter 4 of this datasheet gives technical support when using the TSH343 as
Y-Pb-Pr driver for video DAC output on a video line (see TSH344 for RGB signals). The
TSH343 is available in the compact SO8 plastic package for optimum space-saving.
