Pin Description
PIN BYPASS PIN 16 I/O I DESCRIPTION
Tap to voltage divider for internal midsupply bias generator used for analog reference Places the amplifier in fade mode if a logic low is placed on this terminal; normal operation if a logic high is placed on this terminal. Analog power supply ground Left channel negative input for fully differential input. Left channel positive input for fully differential input. Left channel negative audio output. Left channel positive audio output. No connection Power ground Supply voltage terminal for power stage Right channel negative input for fully differential input. Right channel positive input for fully differential input. Right channel negative audio output Right channel positive audio output Output control. When this terminal is high, SE outputs are selected. When this terminal is low, BTL outputs are selected.
