PRODUCT OVERVIEW
The DAC-HP Series are high-resolution hybrid digitalto-analog converters with voltage outputs. The Series
has 16-bit binary resolution with ±0.003% integral
nonlinearity. These units are self-contained, including
a low-tempco Zener reference circuit and an output
amplifier, in a miniature 24-pin DDIP package.
circuit. This eliminates code dependent ground
currents by routing currents 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 amplifier track the
ladder network resistors, enhancing temperature
stability and performance. The excellent tracking
of the resistors results in tempcos for differential nonlinearity, gain and zero of ±2, ±15 and
±5ppm/°C max., respectively.
The DAC-HP Series offers both unipolar and bipolar
modes with outputs of 0 to +10V and ±5V respectively. Devices with a bipolar output range of ±10V
are also available and are designated with a "-1"
suffix after the model designation. Input coding is
complementary binary and complementary offset
binary.
The DAC-HP Series operates off of ±15V supplies
and offers models with temperature performance
covering the 0 to +70°C commercial or –55 to
+125°C military temperature ranges. High reliability MIL-STD-883 versions are also available.
The DAC-HP design incorporates thin and thickfilm hybrid technology. The design also includes an
on-board amplifier and a precision Zener reference

TECHNICAL NOTES
1. It is recommended that these converters be operated with local supply
bypass capacitors of 1mF (tantalum type) at the +15V and –15V supply
pins. The capacitors should be connected as close to the pins as possible.
In highfrequency noise environments, an additional 0.01mF 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 ±10mA 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.

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.
Footnotes:
* MAXIMUM OUTPUT CURRENT IS ±10μA
➀ Drive from TTL output with only the DAC-HP as load.
➁ FSR is full-scale range and is 10V for 0 to +10V or –5V to +5V outputs,
20V for ±10V output, etc.
➂ For all models except DAC-HP16BGC.
➃ Settling to ±0.5mV.
➄ ±0.006%FSR/% maximum over full military temperature range for MM and
883 models.
➅ Unipolar output range for suffix “–1” models, 0 to +10V, is reached at the
1/2 scale point.
➆ Pin 17.
➇ For ±12V operation, consult factory.
