leakage for middle voltages

Dec 01, 2005voltage drop across the RTD gets differentially mux'd, too. A 24-bit delta-sigma ADC digitizes the voltage drop across the 270, then the voltage across the RTD, and does the math. We're getting errors in the tens of PPM, tolerable, but we're curious where they're coming from. The sensitivity analysis math here is a nuisance.
