Register Operation
Reset the output to 0 with MSB = 0; reset the output to midscale with MSB = 1.
Load the input register with data bits.
Load the DAC register with the contents of the input register.
The input and DAC registers are transparent.
When LDAC and WR are tied together and programmed as a pulse, the data bits are loaded into the input register
on the falling edge of the pulse and are then loaded into the DAC register on the rising edge of the pulse.
No register operation.

Function
Active low resets both input and DAC registers. Resets to zero-scale if MSB = 0 and resets to midscale if MSB =
1. Signal level must be ≤V
Digital Input Data Bits D13 to D0. Signal level must be ≤V
Positive Power Supply Input. The specified range of operation is 2.7 V to 5.5 V.
