RINN

8

I

Right channel negative differential audio input

RINP

17

I

Right channel positive differential audio input

ROSC

18

I

A resistor connected to this terminal sets the oscillation frequency in conjunction with COSC. For proper

operation, connect a 120 k

Ω resistor from ROSC to ground.
