... DIN Figure 3. Detailed Serial-Interface Timing Diagram Applications Information The MAX5223 is specified for single-supply operation with V ranging from +2.7V to +5.5V, covering all DD commonly used supply voltages in +3V and +5V sys- tems. An internal POR circuit forces the outputs to zero scale and initializes all internal registers to zero. Perform an initial write operation to set the outputs to the desired voltage at power-up ...
