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.
