Part Number: DAC8552
DAC8552's output keeps at level before power down, so I can't control the behaviour of my startup.
Hello,I guess the register is not configured properly, Please check your 3-wire serial timing(SERIAL WRITE OPERATION in datasheet).
DIN: Data is clocked into the 24-bit input shift register on the falling edge of the serial clock input
Try to add longer delay after SYNC is low and the first falling edge of SCKL , and lower SCLK frequency to check it is helpful or not.
