APPLICATION INFORMATION (continued)
The device latches data on the positive edge of WE. It must be enabled with CS low. LDAC low updates the
DAC with the value in the holding latch. LDAC is an asynchronous input and can be held low, if a separate
update is not necessary. However, to control the DAC using the load feature, LDAC can be driven low after the
positive WE edge.
