AK4393 Serial Configuration Problem

[Aoxomox]

Hi all,

I have a current problem using an AK4393 24Bit DAC in serial control mode.

P/S- Pin is configured for serial control -> tied to GND.
All other pins like CKS0..2, DIF0..2, and DFS are also tied to GND as they are internally ored with the register bits.

On the /CSN pin I connected /CS, CCLK and CDTI to an Atmel uC.
The format I send is sampling on falling edge.
The /PDN pin is set low after Power up, and then set high before I start writing to the device.

But no matter what I do it does not react to my write attempts to the serial port.


Has anyone experience with this chip?

Any advice is very welcome.

Thanks, Aoxomox
