Description
Rch Analog Input Pin
Lch Analog Input Pin
NC Pin
No internal bonding.
Common Voltage Output Pin
Normally connected to AGND with a 0.1
μ
F ceramic capacitor in parallel with an
electrolytic capacitor less than 2.2
μ
F.
Analog Ground Pin, 0V
Analog Power Supply Pin, +4.5
+5.5V
Digital Power Supply Pin, +2.7
+5.5V(fs=48kHz), +4.5
+5.5V(fs=96kHz)
Digital Ground Pin, 0V
Serial Data Output Pin
Data bits are presented MSB first, in 2’s complement format.
This pin is “L” in the power-down mode.
Left/Right Channel Select Pin
The fs clock is input to this pin.
Master Clock Input Pin
Serial Data Input Pin
Output data is clocked out on the falling edge of SCLK.
Power-Down Pin
When “L”, the circuit is in power-down mode.
The AK5380 should always be reset upon power-up.
Serial Interface Format Pin
“L”: MSB justified, “H”: I
