Serial, 8-bit, 12-bit interfaces are available. The DAC4815 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 bipolar ±10V output range. The DAC4815 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 bipolar zero. This feature is useful for power-on reset or system calibration. The DAC4815 is packaged in a 28-pin plastic DIP rated for the –40°C to +85°C extended industrial temperature range. High-stability laser-trimmed thin film resistors assure high reliability and true 12-bit integral and differential linearity over the f...
