Footnotes
FSR is full-scale range and is 10V for 0 to +10V or –5V to +5V outputs, 20V for
±10V output, etc.
Initial gain and offset errors are trimmable to zero. See Connection Diagrams.

feedback, the settling time is 4μs.

TECHNICAL NOTES
1. The DAC-HZ12 Series converters are designed and factory
calibrated to give ±1/2LSB linearity (binary version) and
±1/4LSB linearity (BCD version) with respect to a straight
line between end points. This means that if zero and full
scale are exactly adjusted externally, the relative accuracy
will be ±1/2LSB (±1/4LSB, BCD version) everywhere over
the full output range without any additional adjustments.
2. These converters must be operated with local supply by-
pass capacitors from +15V to ground and –15V to ground.
Tantalum type capacitors of 1μF are recommended and
should be mounted as close as possible to the converter.
If the converters are used in a high-frequency noise
environment, a 0.01μF ceramic capacitor should be used
across each tantalum capacitor.
3. When operating in the current output mode, the equivalent
internal current source of 2mA (1.25mA, BCD) must drive
both the internal source resistances and the external load
resistor. A 300ns output settling time is achieved for the
voltage across a 100
load resistor; for higher value
resistors the settling time becomes longer due to the output
capacitance of the converter. For fastest possible voltage
output for a large transition, an external fast-settling
amplifier such as DATEL’s AM-500 should be used in the
inverting mode. Settling time of less than 1μs can be
achieved. See application diagram.
CALIBRATION PROCEDURE
1. Select the desired output range and connect the converter
as shown in the Output Range Selection tables and the
connection diagrams.
2. To calibrate, refer to the coding tables. Note that
complementary coding is used.
3.
Zero and Offset Adjustments
For unipolar operation set all digital inputs to "1" (+2.0 to
+5.5V) and adjust the ZERO ADJUST potentiometer for
zero output voltage or current. For bipolar operation set all
digital inputs to "1" and adjust the OFFSET ADJUST
potentiometer for the negative full scale (for voltage out) or
positive full scale (for current out) output value shown in the
coding table.
4.
Gain Adjustment
Set all digital inputs to "0" (0V to +0.8V) and adjust the
GAIN ADJUST potentiometer for the positive full scale (for
voltage out) or negative full scale (for current out) output
value shown in the coding table.
