The DAC708 and DAC709 are current and voltage output models respectively and are in 24-pin hermetic DIPs. Input coding is Binary Two’s Complement (bipolar) or Unipolar Straight Binary (unipolar, when an external logic inverter is used to invert the MSB). In addition, the DAC708/709 can be loaded serially (MSB first). The DAC707 is designed to interface to a 16-bit bus. 8-Bit (DAC708, 709) or 16-Bit (DAC707) Serial Data Low Byte Latch High Byte Latch D/A Latch Reference Circuit 16-Bit D/A Converter Bipolar Offset Data is written into a 16-bit latch and subsequently the D/A latch. The DAC707 has bipolar voltage output and input coding is Binary Two’s Complement (BTC). All models have Write and Clear control lines as well as input latch enable lines. In addit...
