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.
