LA4168M
Record/Playback System for Microcassette and
Compact Cassette Recorders
Overview
The LA4168M is a record/playback system IC for
microcassette and compact cassette recorders. The
LA4168M is an extremely high-functionality IC that
includes a motor control governor circuit, a voice sensor
circuit that detects sounds and turns motor on or off, a
power switch control circuit that receives an electrical
signal from a photosensor and turns all of the IC function
blocks on or off, and a circuit that increases the speed of
the motor during playback.
Features
鈥?Includes a voice switch that can turn the governor on or
off.
鈥?Includes a power switch circuit that can turn all the IC
function blocks on or off from a photosensor signal.
During record, the IC can automatically turn the
governor on or off according to the microphone input
level, and furthermore, the governor on/off level can be
continuously adjusted from an external control knob.
(The control used for volume adjustment during
playback.)
鈥?Continuously variable microphone monitor level.
