AK4393 Serial Configuration Problem
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.
