V5 - Improving temperature compensation
The graphs for both ADC and DAC gains are all close to a straight a line, so a simple 2 point temperature correction calibration would reduce these errors by at least an order of magnitude.
Consider the above suggestion for a straight line software gain correction, instead of the existing single point gain correction. This requires no hardware changes, and the driver modifications could handle boards calibrated with either a single or double point gain correction.
