4.3 Analog I/O

The NextMove ES provides:

HTwo 12-bit resolution analog inputs.

HFour 12-bit resolution analog outputs.

4.3.1Analog inputs

The analog inputs are available on pins a28 & b28 (AIN0) and a27 & c28 (AIN1).

HDifferential inputs.

HVoltage range: ±10V.

HResolution: 12-bit with sign.

HInput impedance: 120kΩ.

HSampling frequency: 4kHz maximum, 2kHz if both inputs are enabled.

The analog inputs pass through a differential buffer and second order low-pass filter with a cut-off frequency of approximately 1kHz.

Both inputs are normally sampled at 2kHz. However, an input can be disabled by setting ADCMODE to 4 (_acOFF). With one input disabled, the remaining input will be sampled at 4kHz. In MintMT, analog inputs can be read using the ADC keyword. See the MintMT help file for full details of ADC, ADCMODE and other related ADC... keywords.
