Description
Singleended or differential inputs
Voltagerange: software s electable 0-5V,±5V, 0-10V, ±10V
Resolution: 12-bit with sign (accuracy ±4.9mV @ ±10V input)
Inputimpedance: >5k
Samplingfrequenc y: 2.5kHz
Shieldedtwis ted pairs should be used and connected as shown in Figure 1. The shield
connection should be made at one end only. The analog inputs pass through a differential
bufferand sec ond order Butterworth filter with a cut-off frequency of 1kHz . Both the filtered
andunfiltered s ignals are converted using a multiplexed 12-bit ADC. This has fourinput
voltageranges thatcan be selected in MintMT us ing the ADCMODE keyword.
