2 / 5 page KA8602B LOW VOLTAGE AUDIO AMPLIFIER PIN CONFIGURATION Fig. 2 PIN DESCRIPTION ABSOLUTE MAXIMUM RATINGS 1 2 3 4 8 7 6 5 KA8602B INPUT(+) INPUT(-) OUTPUT1 Vcc RIPPLE REJECTION MUTE OUTPUT2 GND Pin No Symbol 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 (VCC - 0.7V)/2. 4 VCC 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 o out of phase with that at output1. The DC level is (VCC - 0.7V)/2. 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 operation. When at a logic “High” (2.0 to VCC volts), the IC is disabled. If Mute is 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.
