Analog inputs are connected to the ADC-16 through the female D25 connector. The connections are as follows:
Pin 12 is a stable 5 V output primarily intended for powering transducers such as thermistors. The amount of current that can be drawn out of this pin varies between computers. Almost all computers should be able to supply 1 mA and most several times this. If too much current is drawn from this pin, the voltage will drop below 5 V and the ADC-16's operation cannot be guaranteed. No attempt should be made to draw more than 10 mA, as permanent damage to the ADC-16 could result. This means that loads of lower than 500 ohms must not be connected. Similarly, this pin must not be driven by external voltages.
