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/Ојs unity-gain buffer ideal
for driving analog-to-digital converters (ADCs) and …
