AN3501NFBP
Luminance, chroma and linear audio signal processing IC for VCR
n Overview
The AN3501NFBP is a luminance, chroma signal
processing IC for VCR (PAL and NTSC). It also inte-
grates a playback equalizer and an NTSC playback cir-
cuit.
A normal audio signal recording/playback circuit is
added so as to design a signal processing PCB in common
for both a HiFi and a normal model, resulting in space
saving of equipment.
This IC is a completely adjustment-free device which
has been realized by introducing a adjustment-free tech-
nology such as a Zener zap, and contributes to a more
efficient design/development and production of an equip-
ment.
