Reference Supply
An internal 6.3V reference is provided on board the
HI-DAC80V/HI-DAC85V. The voltage (pin 24) is accurate to
±
0.8% and must be connected to the reference input (pin 16)
for specified operation. This reference may be used exter-
nally, provided current drain is limited to 2.5mA. An external
buffer amplifier is recommended if this reference is to be
used to drive other system components. Otherwise, varia-
tions in the load driven by the reference will result in gain
variations of the HI-DAC80V/HI-DAC85V. All gain adjust-
ments should be made under constant load conditions.

TABLE 3. GAIN AND OFFSET CALIBRATIONS
UNIPOLAR CALIBRATION
Step 1:
Offset
Turn all bits OFF (11 . . . 1)
Adjust R2 for 0V out
Step 2:
Gain
Turn all bits ON (00 . . . 0)
Adjust R1 for FS - 1 LSB
That is:
4.9988 for 0 to +5V range
9.9976 for 0 to +10V range
BIPOLAR CALIBRATION
Step 1:
Offset
Turn all bits OFF (11 . . . 1)
Adjust R2 for Negative FS
That is:

Step 2:
Gain
Turn all bits ON (00 . . . 0)
Adjust R1 for Positive FS - 1 LSB
That is:
+9.9951V for
±
10V Range
+4.9976V for
±
5V Range
+2.4988V for
±
2.5V Range
This Bipolar procedure adjusts the output range end points. The
maximum error at zero (half scale) will not exceed the Linearity
Error. See the “Accuracy” Specifications.
