Sanyo LA7282 Specifications

Ordering number:ENN4040

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 (0.1 F) for the line amplifier inputs (PB IN and AUDIO IN)

Non-Adjustment of PB Gain by less gain scatter.

Monolithic Linear IC
