LA4167M
Overview
The LA4167M is a record/playback system IC supporting microcassette and compact cassette recorders. This is a
high-performance IC that has on-chip a governor circuit for motor control, a voice sensor circuit that detects sounds and
switches the motor on and off, and a cue-tone circuit for instantly finding the desired segment to play back.
Features
Can switch between recording and playback with a single mechanical switch.
Pause switch can switch the governor on and off.
Cue-tone switch can record specified oscillator output (sine wave) during recording.
The governor can automatically be switched on or off according to the mike input level during recording, and the on/off
level for the governor can be varied continuously by the external volume control (used to adjust volume during playback).
Mike monitor level is continuously variable.
LED pin for turning off the LED only when cue-tone is on.
