Description
The TSH120 is a video buffer that includes a
voltage feedback amplifier with an internal gain of
6dB, rail-to-rail output, internal input biasing and
SAG correction. A power down function offers a
sleep mode with ultra low consumption.
The TSH120 also features an internal
reconstruction filter in order to attenuate the
parasitic 27MHz frequency from the clock of the
video DAC.
