GENERAL DESCRIPTION
The DAC-HP Series are high-resolution hybrid digital-to-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.
The DAC-HP design incorporates thin and thick-film hybrid
technology. The design also includes an on-board amplifier
and a precision Zener reference 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.
