PRODUCT OVERVIEW
The DAC-HZ Series are high-performance,
monolithic, 12-bit binary and 3-digit BCD, digital-
to-analog converters. The DAC-HZ Series are com-
plete and self-contained with a precision internal
reference and fast output operational amplifier. Pin
programmable output voltage and current ranges
are provided for a high degree of application flex-
ibility; the binary versions offer 5 output voltage
ranges and two current ranges while the BCD
models offer 3 and 1 output ranges, respectively.
The DAC-HZ Series contains a precision embedded
Zener reference circuit. This eliminates code-
dependent ground currents by routing current from
the positive supply to the internal ground node
as determined by the R-2R ladder network. The
internal feedback resistors for the on-board ampli-
fier track the ladder network resistors, enhancing
temperature performance. The excellent tracking
of the resistors results in temperature coefficients
for differential nonlinearity, zero and gain of ±2, ±3
and ±20ppm/°C maximum, respectively.

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 bypass capaci-
tors 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 100Ω 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. Set-
tling time of less than 1μs can be achieved. See application diagram.
CALIBRATION PROCEDURE
Select the desired output voltage range and connect the converter as shown
in the Output Range Selection Table and the Connection Diagrams. Refer to
the Coding Tables.
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.
