Audio Level Sensor

Overview

LA2000 is an IC for detecting interprogram spaces to pick out

the starting point of a program immediately preceding or

following a musical program recorded on tape, and to detect

end of tape.

Used in

.

Radio-cassette recorders

.

Cassette decks

.

Car stereos

Applications

.

Detection of spaces between programs recorded on tape

.

Detection of end of tape

.

Other

Features

.

Has transistors capable of driving plungers with maximum

600 mA, and a protective diode to prevent induced reverse

voltages.

.

Can provide designated time delays by externally connected

capacitors and resistors.

.

Has a comparator with stable hysteresis to handle variations

in power supply voltage.

.

Detects unrecorded portions of tape.
