The ML2340 and ML2350 are CMOS voltage output, 8-bit D/A converters with an internal voltage reference and a P interface. These devices are designed to be powered by a single supply, although they can be powered from dual power supplies. The output voltage swings above zero scale (VZS) in the unipolar mode or around zero scale (VZS) in the bipolar mode, both with programmable gain. VZS can be set to any voltage from AGND to 2.25V below VCC. The digital and analog grounds, DGND and AGND, are totally independent of each other. DGND can be set to any voltage from AGND to 4.5V below VCC for easy interfacing to standard TTL and CMOS logic families.
