–6 to +2 V in unipolar mode. V
of –6 to +11 V in either mode.
Pins 10 through 12 of the front connector are the AO signals DAC0OUT,
AGND, and DAC1OUT.
DAC0OUT is the voltage output signal for AO channel 0. DAC1OUT is the
voltage output signal for AO channel 1. AGND is the ground-reference
point for both AO channels and analog input.
The following output ranges are available, and for each output range, the
maximum load current is ±1 mA for 12-bit linearity (per DAC):
