Pin Descriptions
Pin Number Name
Function
1
RINN Negative differential audio input for right channel
2
RINP Positive differential audio input for right channel
3
AVDD 5V Analog VDD
4
VREF Analog reference for gain control section
5
VOLUME DC voltage that sets the gain of the amplifier
Ground for gain control circuitry. Connect to AGND. If using a DAC to control the
6
REFGND
volume, connect the DAC ground to this terminal.
7
AGND1 Analog GND
Input for controlling volume ramp rate when cycling SD or during power-up. A
8
FADE ^{logic low on this pin places the amplifier in fade mode. A logic high on this pin}
allows a quick transition to the desired volume setting.
9
