6.2 Analog I/O (GPIO4)
6.2.1 Analog Inputs
The 8 analog inputs have a range of ±10 V, 16 Bit resolution, and a 1.6 MHz 1st order
low pass filter.
In all cases, the analog input values must be within the ±10 V range. The analog input
impedance is typically 47 kΩ. The maximum input current is ±200 µA.
1 LSB = 20 V/65536 ≈ 0.3 mV
The ADC offset and gain errors are compensated.
6.2.2 Analog Outputs
The 8 analog outputs have a configurable full scale ±5 V, ±10 V, or ±12.288 V and 16
Bit resolution. The DAC offset and gain errors are compensated. The output settling
time is typically 15 µs.
Analog outputs are voltage outputs (output current less than 1 mA), so to use them
properly, they must be connected to an impedance higher than 10 kΩ.
1 LSB = 20 V/65536 ≈ 0.3 mV.
Analog outputs can be accessed via the GPIOAnalogSet(GPIO4.DACn,…) function.
