= 5V, 0.47µF ceramic X5R capacitor in parallel with a 10µF aluminum electrolytic capacitor from
Digital Supply Voltage. Connect to 5V.
Device Address Set Input. Connect to G_DIG to set write and read addresses of 94h and 95h,
respectively. Connect to V_DIG to set write and read addresses of 96h and 97h, respectively.

Interrupt Output. INTERRUPT_OUT is an open-drain output that goes high impedance to
indicate a change in the slow switch lines, AUX_SS, TV_SS, or VCR_SS.

Audio Input Bias Voltage. Bypass AUD_BIAS with a 10µF capacitor and a 0.1µF capacitor to
G_AUD.
Audio Supply Voltage. Connect all V_AUD together. An on-board linear regulator creates the
+8V audio supply voltage from V12. Bypass pin 30 with a 10µF aluminum electrolytic capacitor
in parallel with a 0.47µF low-ESR ceramic capacitor to audio ground, and bypass pins 11 and
22 with 0.1µF capacitors to audio ground.
