DESCRIPTION
Unipolar analog inputs. These channels are used for general monitoring and their input range is 0 to 2 x V_REF.
Bipolar analog inputs. Typically used to monitor the DAC_D2 to DAC_D5 outputs. The input range of these channels
is -12.5-V to +12.5-V.
Bipolar analog inputs. Typically used to monitor the DAC_C0 to DAC_C1 outputs. The input range of these channels
is -12.5-V to +12.5-V.
DAC group C. These channels share the same range and clamp voltage.
Negative analog supply for DAC group C. Sets the power-on-reset and clamp voltage values. Typically tied to AVEE
when the DAC range for group C is set to -10 to 0-V or AGND for the positive output ranges.
This terminal determines the DAC range for DAC group C. If tied to AGND the DAC range is 0 to +5-V or 0 to +10-V.
Otherwise if tied to +2.5-V (can be tied to REF_OUT terminals) the DAC range is -10 to 0-V.
Reference output 2. Can be used to drive the VRANGE inputs.
Positive analog power for DAC groups C and D. Must be tied to AV_{CC_AB}.
DAC group D. These channels share the same range and clamp voltage.
Analog ground. Ground reference point for all analog circuitry on the device, AGND. Connect AGND1, AGND2 and
AGND3 to the same potential, AGND.
This terminal determines the DAC range for DAC group D. If tied to AGND the DAC range is 0 to 5-V or 0 to 10-V.
Otherwise if tied to +2.5-V (can be tied to REF_OUT terminals) the DAC range is -10 to 0-V.
Negative analog supply for DAC group D. Sets the power-on-reset and clamp voltage values. Typically tied to AVEE
when the DAC range for group D is set to -10 to 0-V or AGND for the positive output ranges.
The thermal pad is located on the package underside. Should be tied to AV_EE or left unconnected.
