In our design, we are using DAC8728 chipsets to set Analog outputs. The issue is, we are not able to get the output range of -10V to +10V.
Applied voltage details for DAC8728 are : AVDD = +15V, AVSS = -15V, DVDD = +3.3V, IOVDD = +3.3V, REF : +5V, LDAC = 0V, USB/RTC = +3.3V, RST SEL : +3.3V
DAC OFFSET value = 0x999A (default)
DAC offset Voltage on pin 12 : +3.8V
When DAC set value is 0x0000, Measured voltage at DAC Outx : +5.628V
Set Value is 0x7FFF, measured voltage is +6.423V
Set Value is 0x8000, measured voltage is -14.967V
Set Value is 0xFFFF, measured voltage is +5.628V
What should we do to achieve the output range of -10V to +10V? what is value to get 0V at DAC output?
Kindly guide us to resolve the issue.
