3.2.1 Analog Input, Single Ended - X11
Location Connector X11, pins 1 & 2
Name AIN2
Mint keyword ADC.2
Description Single ended input.
Range: 0 - ±10VDC.
Resolution: 9 -bit with sign.
Input impedance: >4kΩ.
Sampling interval: 5ms.
Note: There is a +15V reference voltage supplied on X11 pin 3 from a 1.96kΩ resistor.
A linear command potentiometer of 5kΩ may be used, with X11 pin 2 connected to the wiper,
and the end terminations connected to pins 1 & 3, as shown below.
