KA8602B
INTRODUCTION
LOW VOLTAGE AUDIO AMPLIFIER
8-DIP-300
The KA8602B is the audio power amplifier available for
low voltages. KA8602B supplies differential outputs for max-
imizing output swing at low voltages. KA8602B doesn't
need coupling capacitors to the speaker. The gain of
this amp is controlled easily by two external resistors.
