Description

The TSH122 is a video buffer that uses a voltage feedback amplifier, with an internal gain of 6 dB, an output rail-to-rail, an internal input DC-shift and a SAG correction. A power-down function allows

switching to a sleep mode with an ultra-low consumption.

Features

■ Very low consumption: 1.7 mA

■ Ultra low power-down mode: 4 nA typ., 500 nA max.

■ Internal 6th order reconstruction filter
