Monolithic Linear IC
Recording/Playback Amplifier for VHS VCRs
The LA70011 and LA70011M are recording/playback
amplifiers for VHS VCR video signals. When used in
combination with the LA71000M and LA71500M Series
of video signal processing ICs, they permit Y/C recording
without current adjustment.
• Connecting the playback amplifier input directly to the
head reduces the number of external elements required.
• The recording amplifiers use a fixed-current drive
configuration that yields stable recording characteristics
even under changing loads. They include built-in
automatic gain control circuits.
• Using the same dimensions and pin assignments as the
LA70001 and LA70001M permits the use of the same
circuit boards as these earlier chips. The LA70011 can
also be mounted at the right end of an LA70020 socket.
