■
Dither
The AK4125 has a dither circuit. The dither circuit adds the dither to the LSB of the output data, which is the value of the
OBIT1-0 pins, by DITHER pin = “H” regardless of the SRC mode or the SRC bypass mode.
■
System Reset
Bringing the PDN pin = “L” sets the AK4125 power-down mode and initializes the digital filter. The AK4125 should be
reset once by bringing the PDN pin = “L” when power-up. When the PDN pin = “L”, the SDTO output is “L”. The SDTO
valid time is 100ms. Until the output data becomes valid, the SDTO pin outputs “L”.
