DESCRIPTION
Symbol Description Analog Ground amplifiers. 1.0µF capacitor this (with 5.0µF Input capacitor provides 52dB (Typ) power supply rejection. Turn-on time circuit affected capacitor this pin. This used alternative input. Input Output Output Amplifier input. input capacitor resistor frequency roll-off input impedance. feedback resistor connected between this output1. Amplifier output. Level Ground pin. Amplifier output. This signal equal amplitude, phase with that output1. level

(VCC 0.7V)/2.
This used power down conserve power, muting, Mute both. When logic "Low" volts), KA8602B enabled normal operation. When logic "High" (2.0 volts), disabled. Mute open, that equivalent logic "Low". Ripple Rejection capacitor this increases power supply rejection, affects turn-on time. This left open capacitor sufficient.
