THS7347 - Texas Instruments

THS7347 3-Channel RGBHV Video Buffer

Fabricated using the revolutionary complimentary silicon-germanium (SiGe) BiCom3 process, the THS7347 is a low-power, single-supply 2.7-V to 5-V 3-channel integrated video buffer with horizontal (H) and vertical (V) sync signal paths. It incorporates a 500-MHz bandwidth, 1200-V/μs unity-gain buffer ideal for driving analog-to-digital converters (ADCs) and vi.
