AD7392/AD7393 THEORY OF OPERATION The AD7392/AD7393 comprise a set of pin-compatible, 12-/10- bit digital-to-analog converters (DACs). These single-supply operation devices consume less than 100 μA of current while operating from 2 5.5 V power supplies, making them ideal ...
Page 13
POWER SUPPLY The very low power consumption of the AD7392/AD7393 is a direct result of a circuit design that optimizes the CBCMOS process. By using the low power characteristics of CMOS for the logic and the low noise, tight-matching of ...

BIPOLAR OUTPUT OPERATION Although the AD7393 is designed for single-supply operation, the output can be easily configured for bipolar operation. A typical circuit is shown in Figure 33. This circuit uses a clean, regulated 5 V supply for power, which ...
