The DAC2815 is one in a family of dual and quad 12bit digital-to-analog converters (DACs). Serial, 8-bit, 12-bit interfaces are available. The DAC2815 is complete. It contains CMOS logic, switches, a high-performance buried-zener reference, and low-noise bipolar output amplifiers. No external components are required for either unipolar 0 to 10V, 0 to 10V, or bipolar 10V output ranges. The DAC2815 has a 2-byte (8 + 4) double-buffered interface. Data is first loaded (level transferred) into the input registers in two steps for each DAC. Then both DACs are updated simultaneously. The DAC has an asynchronous clear control for reset to unipolar or bipolar zero depending on the mode selected. This feature is useful for power-on reset or system calibration. The DAC2815 is packaged in a 28-pin plastic DIP rated for the 40C to +85C extended industrial temperature range.
