2 V in unipolar mode. Vin+ should remain within a range of –6 to +11 V in
either mode.
Analog Output Signal ConnectionsPins 10 through 12 of the front connector are the analog output signals
DAC0OUT, AGND, and DAC1OUT.
DAC0OUT is the voltage output signal for analog output channel 0.
DAC1OUT is the voltage output signal for analog output channel 1. AGND
is the ground-reference point for both analog output channels and analog
input.
The following output ranges are available:
• Output signal range
–Bipolar output ±5 V*
–Unipolar output 0 to 10 V*
*Maximum load current ±1 mA for 12-bit linearity (per DAC)
Figure3 -7 shows how to make analog output signal connections.
