DAC709

The DAC708 and DAC709 are 16-bit converters designed to interface to an 8-bit microprocessor bus. 16- bit data is loaded in two successive 8-bit bytes into parallel 8-bit latches before being transferred into the D/A latch. 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 DAC709 is designed to interface to a 16-bit bus. 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 addition, DAC708 and DAC709 have Chip Select control lines. In the bipolar mode, the Clear input sets the D/A latch to give zero voltage or current output. They are all 14-bit accurate and are complete with reference, and for the DAC707, and DAC709, a voltage output amplifier. All models are available with an optional burn-in screening.
