12 Shield Shield connection
The analog inputs are available on breakout module connector X6. Shielded twisted pairs
should be used and connected as shown in Figure 1. The shield connection should be made
at one end only.
H Single ended or differential inputs.
H Voltage range: software selectable 0-5 V, ± 5 V, 0-10 V, ±10 V
H Resolution: 12-bit with sign (accuracy ±4.9 mV @ ±10 V input).
H Input impedance: >5 kΩ.
H Sampling frequency: 2.5 kHz
The analog inputs pass through a differential buffer and second order low-pass filter with a
cut-off frequency of approximately 1 kHz. Four input voltage ranges can be selected in Mint
using the ADCMODE keyword. Analog inputs can be read using the ADC keyword. See the Mint
help file for full details of ADC, ADCMODE and other related ADC... keywords.
