1 DVSS - Digital Ground Pin 15 BVSS I Substrate Ground Pin, 0V
2 DVDD - Digital Power Supply Pin, 3.3V or 5.0V 16 VREFL I Low Level Voltage Reference Input Pin
3 MCLK I Master Clock Input Pin 17 VREFH - High Level Voltage Reference Input Pin
4 PD I Power-Down Mode Pin 18 AVDD - Analog Power Supply Pin,5V
When at "L",the Ak4393 is in power-down
mode and is held in reset.
The AK4393 should always be reset
upon power-up.
5 BICK I Audio Serial Data Clock Pin 19 AVSS O Analog Ground Pin, 0V
