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.
