LA70020 Datasheet, PDF (1/13 Pages) Sanyo Semicon Device – Recording/Playback Amplifier for VHS VCRs

Ordering number : EN5711A
Monolithic Linear IC
LA70020, 70020M
Recording/Playback Amplifier for VHS VCRs
Overview
The LA70020 and LA70020M are 6-head amplifiers
adding hi-fi recording/playback amplifiers to the
LA70011/LA70011M 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.
Features
• Combining hi-fi and video amplifiers onto a single chip
saves space on the circuit board.
• 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.
• The LA70020, encapsulated in DIP package, can be
mounted at the right end of the LA70001 and LA70011
sockets. The LA70020M lacks this flexibility because its
MFP package has a different pin pitch.
