... The parallel data interface DD consists write strobe and 12 data bits (D0 to D11) if utilizing the AD7392 or 10 data bits (D0 to D9) if utilizing the AD7393 pin is available to reset the DAC register to zero scale. This function is useful for power-on reset or system failure recovery to a known state. Additional power savings are accomplished by activating the SHDN pin, resulting in a 1.5 μ ...

... V The micropower REF195 is guaranteed to source 10 mA output drive current, but consumes only 50 μA internally. If higher resolution is required, the AD7392 can be used with two additional bits of data inserted into the software coding, which results in a 2.5 mV LSB step size. Table 8 shows examples of nominal output voltages (V operation circuit application ...
