Playback Amplifier and Record Amplifier
for VHS VCRs
Overview
The LA7411 and LA7411M are playback and record amplifier
IC for two-head VHS VCRs. When used in conjunction with
the video signal processing ICs of the LA7420/30 series, it is
possible to eliminate the need to adjust the Y/C record current.
Functions
.
2-channel playback amplifier.
.
1-channel record amplifier.
.
REC/PB mode switching head switch circuit.
.
Envelope wave detection (for auto-tracking).
Features
.
The record amplifier provides stable record characteristics in
constant current drive mode, which is able to withstand load
fluctuations. In addition, the built-in AGC eliminates the
need to adjust the record current.
.
Designed to share printed circuit boards with the
LA7416/7416M (for 4-head systems).
