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.
