I'm trying to set AD5752RBREZ (I use internal DAC reference) with Atmega16, but it is not working. It gives no output voltage. Between every step I have a delay. I would like to use bipolar output DAC A with range +-10,8V. Analog power supply is 15V, digital 5V. I don't use SDO output. I have connected SYNC, SCK, LDAC, CLR, SDIN with Atmega16.
My algorithm is:
WriteByte(0b00000011) - The first I set Power control register
The same for Output range select register, I send:
After that I send data to DAC Register, for example 0x001A30
What could be wrong? Thanks.
