We are facing problem regarding SPI communication with AD5062 DAC .
we followed the data communication sequence as per the datasheet .
Ref voltage given to IC is 4.094V.
Pass the digital counts & got the analog voltage as mentioned below-
Count = 8000 , Output Voltage = 0.499 V
Count = 16000 , Output Voltage = 0.999 V
Count = 24000 , Output Voltage = 2.04 V
Count = 32000 , Output Voltage = 2.04 V
Count = 40000 , Output Voltage = 2.49 V
Count = 48000 , Output Voltage = 4.019 V
Count = 56000 , Output Voltage = 4.007 V
Count = 64000 , Output Voltage = 3.99 V
please provide the appropriate count setting to get full scale output at final count.
Hi,I moved your query to its proper community Precision DACs.Best Regards,Goz
What is your VDD?
Can you send scope shots of your digital signals (SYNC,SCLK,DIN) for the counts that you have enumerated above?
Solved the issue.
