The A/D converter inputs can also be used with 4–20 mA current sources by measuring the
resulting analog voltage drop across 249 Ω 1% precision resistors placed between the ana-
log input and analog ground for ADC_IN3 to ADC_IN6. Be sure to reconfigure the
jumper positions on header JP8 as shown in Section B.1.8 using the slip-on jumpers
included with the spare parts in the Development Kit.
B.1.5.2 Thermistor Input
Analog input THERM_IN7 on the Prototyping Board was designed specifically for use
with a thermistor in conjunction with the
strates how to use analog input THERM_IN7 to calculate temperature for display to the
Dynamic C
included with the Development Kit with R
to use the applicable R
Install the thermistor at location J7, which is shown in Figure B-4.
