Serial Timing Diagram
Programming Model
The device has power-on reset that disables outputs, disables test mode, and turns off analog currents. To start up the device the
control word is sent:
It is important to always program control bits 2-8 as zeros to avoid activating test modes designed for device manufacturing.The
clamp bit activates the input clamp and bleed current sink and works only in the single-ended version.
To enable individual outputs, the output enable control word is sent. There are 16 enables to set; this is done with serial words
controlling four at a time. The output enable control word format is:
The O
x
bits represent output enables of eight individual registers. The N1 and N0 bits represent a two bit binary number which is
used in setting n = 2
N1N0
. For instance, to access the control bit of the 5th output enable, we send the word:
Individual output enables are ended with the control register’s common output enable bit and the power on bit.
