Temperature drift of the IDAC is not normally spec present in the datasheet. Could you please let us know what you are trying to do?
Simplified, I am using the IDAC in combination with a resistor and an Opamp (Buffer) to generate a voltage over another variable resistor. Simultanouesly, I am measuring the current through the variable resistor to calculate the power dissipation.
I want to keep the electrical power constant for futher regulation processes. To calculate the tolerances of this regulation, I need to know all drift parameters.
The drift value spec of the component is 10% (conditions -45 to 130C and 1.7V to 5.5V and across all corners). This is the worst case value and the actual device performance might be much better.
