TSH345IPT

Overview

The TSH345IPT is a triple single-supply video buffer designed for HD and SD video applications. It features an internal gain of 6 dB and selectable 6th order filtering with cutoff frequencies at 36 MHz, 18 MHz, and 9 MHz. The device operates on a single 5 V power supply and includes an internal input DC level shifter to optimize signal linearity without requiring external input capacitors. It is specified for 150 Ω loads and supports AC or DC output coupling.
