Description

1

Input (+)

Analog Ground for the amplifiers. A 1.0

µF capacitor at this pin (with a 5.0µF

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.

2

Input (-)

Amplifier input. The input capacitor and resistor set low frequency roll-off and input

impedance. The feedback resistor is connected between this pin and output1.

3

Output 1

Amplifier 1’s output. The DC Level is

4

DC supply voltage (+2.0 ~ + 16V) is applied to this pin.

5

GND

Ground pin.

6

Output 2

Amplifier 2’s output. This signal is equal in amplitude, but 180

that at output1. The DC level is

7

Mute

This pin can be used to power down the IC to conserve power, or for muting, or

both. When at a logic “Low” (0 to 0.8 volts), the KA8602B is enabled for normal

open, that is equivalent to a logic “Low”.

8

Ripple

Rejection

A capacitor at this pin increases power supply rejection, and affects turn-on time.

This pin can be left open if the capacitor at pin 1 is sufficient.
