Cautions And Application Method

(description is made only on the single channel.)

1. Voltage gain adjustment

This IC has the amplifier construction as shown Fig.1. The pre−amp (amp 1) is provided to the primary stage,

and the input voltage is amplified by the flat amps, amp 3 and amp 4 of each channel through the phase amp

(amp 2).

Since the input offset is prevented by pre−amp when VCC is set to on, this circuit can remarkably reduce the pop

noise.
