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 externalcomponents 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-bufferedinterface. Data is first loaded (level transferred) intothe input registers in two steps for each DAC. Thenboth DACs are updated simultaneously. The DAC hasan asynchronous clear control for reset to unipolar orbipolar zero depending on the mode selected. Thisfeature is useful for power-on reset or system calibra-tion. The DAC2815 is packaged in a 28-pin plasticDIP rated for the –40°C to +85°C extended industrialtemperature range.High-stability laser-trimmed thin film resistors assurehigh reliability and true 12-bit integral and differentiallinearity over the full specified temperature range.DUAL 12-BIT DIGITAL-TO-ANALOGCONVERTER (8-Bit Port Interface)● HIGH-SPEED 8 + 4-BIT PARALLELINTERFACE● LOW POWER: 300mW (150mW/DAC)● LOW GAIN DRIFT: 5ppm/°C● LOW NONLINEARITY: ±1/2 LSB max● UNIPOLAR OR BIPOLAR OUTPUT● CLEAR/RESET TO UNIPOLAR ORBIPOLAR ZERO®International Airport Industrial Park • Mailing Address: PO Box 11400 • Tucson, AZ 85734 • Street Address: 6730 S.
