Monolithic Linear IC
LA7282, 7282M
VCR Audio Signal Recording /
Playback Processor
Overview
The LA7282 and 7282M are small package ICs containing
all functions necessary to record and playback VCR audio
signal.
Features
• Small package leaves large space for other components.
• Delete of In and Output electrolysis capacitor.
• Low capacitor (0.1µF) for the line amplifier inputs (PB
IN and AUDIO IN)
• Non-Adjustment of PB Gain by less gain scatter.

give rise to accidents or events that could endanger human lives, that could give rise to smoke or fire,
or that could cause damage to other property. When designing equipment, adopt safety measures so
that these kinds of accidents or events cannot occur. Such measures include but are not limited to protective
circuits and error prevention circuits for safe design, redundant design, and structural design.
