Hello,
I have an application with the following requirements:
- Using the internal reference (which is 2.5V) with a divider value = 1
- The DAC output gain will be set to 2x
- VDD will be 4.7V
- DAC FSR = 5V @ +/-15mA (max), though we will only drive it between 3.7V and 4.5V maximum.
Questions:
- What will happen if we set the DAC output to 5V with a 4.7V supply? I suspect that the output will saturate at 4.7V - DAC DC Output Resistance x DAC output load current.
- Will there be any potential for damage to the device by leaving it in this condition for a long or short time?
- Do we have any curves that detail the DAC output voltage droop given a specific load current and supply voltage?
