200MHz, Video Op Amp with High Speed
Sync Stripper
The HFA1103 is a high-speed, wideband, fast settling
current feedback op amp with a sync stripping function. The
HFA1103 is a basic op amp with a modiï¬ed output stage that
enables it to strip the sync from a component video signal.
The output stage has an open emitter NPN transistor that
prevents the output from going low during the sync pulse.
Removing the sync signal beneï¬ts digitizing systems
because only the active video information is applied to the
A/D converter. This enables the full dynamic range of the
A/D converter to be used to process the video signal. The
HFA1103 includes inverting input bias current adjust pins
(pins 1 and 5) for adjusting the output offset voltage.
