S/PDIF Output pin. Outputs “L” when PDN Pin = “L”.
Master Clock Output Pin. Outputs “L” when PDN Pin = “L”.
Audio Serial Data Clock Pin.
Input Channel Clock Pin
Audio Serial Data Output 3 Pin
Audio Serial Data Output 2 Pin
Audio Serial Data Output 1 Pin
A 0.68μF capacitor should be connected to GND5 externally.
“L”: 24bit Left justified if IDIF0 bit = “0”(default)
“H”: 24/16 bit IIS
Should be synchronized to LRCK and SCLK when SRC is not used.
Hi-Z when PDN Pin = “L”.
This pin is internally XORed with A4M50 bit (default = “1”).
This pin is internally XORed with A4M51 bit (default = “1”).
When “L”, the AK4141 is powered-down, all registers are reset. And then all
digital output pins go “L”. The AK4141 must be reset once upon power-up.
For through output. No Input Amplifier integrated.
This pin is internally ORed with A4M52 bit (default = “0”).
Outputs “L” when PDN Pin = “L” and MSN Pin = “H”.
Hi-Z when PDN Pin = “L” and MSN Pin = “L”.
Outputs “L” when PDN Pin = “L” and MSN Pin = “H”.
Hi-Z when PDN Pin = “L” and MSN Pin = “L”.
Outputs “L” when PDN Pin = “L”.
Outputs “L” when PDN Pin = “L”.
Outputs “L” when PDN Pin = “L”.
