MAX5105/MAX5106

Nonvolatile, Quad, 8-Bit DACs

_______________________________________________________________________________________ 13

The nonvolatile store command is ignored if all DACs

are muted or in shutdown.

This command directly loads the DAC data to the

selected DAC volatile register and updates the respec-

tive output on the rising edge CLK corresponding to

D0. The mute/shutdown volatile register is also accessi-

ble through this command by setting A2 high. A 1 in

any of the four MSBs (D7–D4) mutes the selected DAC;

a 1 in any of the four LSBs (D3–D0) disables the select-

ed DAC (Table 1). The DAC operating states change
