PRODUCT DESCRIPTION
The ADDAC80 Series is a family of low cost 12-bit digital-to-analog converters with both a high stability voltage reference and output amplifier combined on a single monolithic chip. The ADDAC80 Series is recommended for all low cost 12-bit D/A converter applications where reliability and cost are of paramount importance.
Advanced circuit design and precision processing techniques result in significant performance advantages over conventional DAC80 devices. Innovative circuit design reduces the total power consumption to 300 mW, which not only improves reliability, but also improves long term stability.

FEATURES
   Single Chip Construction
   On-Board Output Amplifier
   Low Power Dissipation: 300 mW
   Monotonicity Guaranteed over Temperature
   Guaranteed for Operation with 12 V Supplies
   Improved Replacement for Standard DAC80, DAC800
      Hl-5680
   High Stability, High Current Output
      Buried Zener Reference
   Laser Trimmed to High Accuracy
      1/2 LSB Max Nonlinearity
   Low Cost Plastic Packaging
