Figure 34 shows the equivalent logic interface for the key digital control pins for the DAC8812.

Figure 34. DAC8812 Equivalent Logic Interface

Two additional pins, RS and MSB, provide hardware control over the preset function and DAC register loading. If

these functions are not needed, the RS pin can be tied to logic high. The asynchronous input RS pin forces all

input and DAC registers to either the zero-code state (MSB = 0), or the half-scale state (MSB = 1).
