Ordering number:EN4091
Monolithic Linear IC
LA7285, 7285M
VCR Audio Signal Recording
and Playback Processor
Overview
The LA7285 and LA7285M include on chip all functions
required for the record and playback of VCR audio
signals. In addition, the inclusion of a switching circuit
for switching between tuner and line input in addition to
the circuits provided by earlier ICs makes the LA7285
truly optimal for audio VCR products.
