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.

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.

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.
BIT 13
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
