Data Sheet
HFA1103
March 1999 File Number 3957.3
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 modified 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 benefits 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.
