TECHNICAL NOTES
1. It is recommended that these converters be operated with
local supply bypass capacitors of 1µF (tantalum type) at the
+15V and –15V supply pins. The capacitors should be
connected as close to the pins as possible. In high-
frequency noise environments, an additional 0.01µF
ceramic capacitor should be used in parallel with each
tantalum bypass.
2. When laying out the circuit board for this device, isolate the
analog, digital and power grounds as much as possible from
each other before joining them at pin 20.
3. If the reference output (pin 24) is used, it must be buffered
by an operational amplifier in the noninverting mode. See
Figure 2. Current drawn from pin 24 should be limited to
±10µA in order that the temperature coefficient of the
reference circuit not be affected. This is sufficient current
for the bias current requirements of most popular
operational amplifier types.

CALIBRATION PROCEDURE
For bipolar operation, connect Bipolar Offset (pin 18) to
Summing Junction (pin 21). For unipolar operation, connect
Bipolar Offset (pin 18) to Ground (pin 20). In making the
following adjustments, refer to the Coding Tables and
Connection Diagrams.
1.
Zero Adjustment.
Set the input digital code to 1111 1111
1111 1111 and adjust the ZERO ADJ. potentiometer to give
0.00000V output for unipolar operation or –FS output for
bipolar operation.
2.
Gain Adjustment.
Set the input digital code to 0000 0000
0000 0000 and adjust the GAIN ADJ. potentiometer to give
+FS – 1LSB output for either unipolar or bipolar operation.
