AN3501NFBP
Luminance, chroma and linear audio signal processing IC for VCR
s Overview
The AN3501NFBP is a luminance, chroma signal processing IC for VCR (PAL and NTSC). It also integrates a playback equalizer and an NTSC playback circuit. 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 technology such as a Zener zap, and contributes to a more efficient design/development and production of an equipment.
