Any and all SANYO products described or contained herein do not have specifications that can handle
applications that require extremely high levels of reliability, such as life-support systems, aircraft’s
control systems, or other applications whose failure can be reasonably expected to result in serious
physical and/or material damage. Consult with your SANYO representative nearest you before using
any SANYO products described or contained herein in such applications.
SANYO assumes no responsibility for equipment failures that result from using products at values that
exceed, even momentarily, rated values (such as maximum ratings, operating condition ranges, or other
parameters) listed in products specifications of any and all SANYO products described or contained
herein.
Overview
The LA4165M Recording-Playback IC combines the
functions required to design the recording and playback
systems and motor control circuits for micro- or
standard-cassette tape recorders into a single chip.
Functions provided include automatic audio input
sensing during recording with stepless setting of the onoff threshold using the playback volume control, and
LED indication that recording is in progress.
Recording and playback modes can be toggled using a
single control pin.
The LA4165M also has an on-chip preamp, power amp
and ALC circuits, and has been designed to operate with
a 3V power supply. The device is available in 24-pin
plastic MFPs.
Features
• Audio input sensor circuit
• LED driver circuit
• Motor control circuit
• ALC circuit
• Preamp and power amp circuits
