Depends on the Vdd voltage and temperature. Sinking (output low) currents are: 5V Vdd and 85C sinking current is 0.42 ma. 10V Vdd and 85C, sinking current is 1.1 ma. 15V Vdd and 86C sinking current is 2.8 ma. Sourcing (output is high) currents are: 5V Vdd and 85C, sourcing current is 0.42 ma. 10V Vd...

The reason you're experiencing this problem is due to the A/D chip used in the DPM. It's likely the 7106 DMP chip, which uses an internal voltage reference. The chip design is such that the low side of this reference must be maintained at a voltage that is above the analog common pin. <p>There are a...
