UTC UTCTA8207K Datasheet

UTC TA8207K LINEAR INTEGRATED CIRCUIT

LOW FREQUENCY POWER
AMPLIFIER

DESCRIPTION

The UTC TA8207K is an audio power IC with built-in two
channels developed for portable radio cassette tape recorder
with power ON/OFF switch.
Because of the parts reduction and SIP (Single inline
package), space merit is remarkable.
Thermal shut down protection circuit is built in.

FEATURES
