Overview
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 maximizing 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.

A 1.
0µF capacitor at this pin (with a 5.
0µF 1 Input (+) capacitor at pin 8) provides 52dB (Typ) of power supply rejection.
Turn-on time of the circuit is affected by the capacitor on this pin.
This pin can be used as an alternative input.

The input capacitor and resistor set low frequency roll-off and input impedance.
The feedback resistor is connected between this pin and output1.
Amplifier 1’ s output.
The DC Level is Ground pin.
Amplifier 2’ s output.
This signal is equal in amplitude, but 180 out of phase with that at output1.
The DC level is l l l l (VCC - 0.
7V)/2.
DC supply voltage (+2.
0 ~ + 16V) is applied to this pin.
o (VCC - 0.
