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. 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.
