The IDAC of SiLabs 'F350 doesn't have so much precision.
Full scale output of 2mA range (mA): 1.6 (min) - 2.0 (typ) - 2.4 (max) Apply ratio-metric measurement when you use this IDAC for the ADC; Connect a reference resistor in series to the load, and take the VREF of the ADC across this reference resistor. For ratio-metric, load regulation of the current source is not so much problem. Tsuneo |
