Figure 6. Daisy-chained or individual MAX532s are simultaneously updated by bringing CS high when using the 3-wire interface
(LDAC = DGND).
Figure 7. Multiple devices sharing a common DIN line may be simultaneously updated by bringing LDAC low. CS1, CS2, CS3, . . .,
are driven separately, thus controlling which data are written to devices 1, 2, 3, . . . .
