DAC-HP

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.
