Product Summary

The DAC-HP16BGC is a resolution hybrid digital-to-analog converter with voltage outputs. The device has 16-bit binary resolution with ±0.003% integral nonlinearity. The DAC-HP16BGC is self-contained, including a low-tempco Zener reference circuit and an output amplifier, in a miniature 24-pin DDIP package. The DAC-HP16BGC offers both unipolar and bipolar modes with outputs of 0 to +10V and ±5V respectively. 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 DAC-HP16BGC 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/℃ max, respectively.
