I would like to use AD5433 with unipolar mode.
And, I use R1 and R2 resistors to adjust the gain.
Please inform me of the expression that calculates this resistors.
The equations in order to calculate the resistors values are as follow:
where: RDACmax is the specified maximum input resistance of the DAC.
For high resolution applications both resistors should be precision resistors with matched temperature coefficients to maintain the circuit performance.
