OUT3A/3B output digital data corresponding to the signal applied on analog input pin IN3.
OUT3A/3B output digital data corresponding to the signal applied on analog input pin IN2.
OUT3A/3B output digital data corresponding to the average of signals applied on analog
input pins IN1 and IN4.
These bits determine which data stream is output on LVDS pins OUT4A/4B
(after global enable bit for averaging is enabled <EN AVG GLO> = 1)
LVDS OUT4A/4B buffers are powered down.
OUT4A/4B output digital data corresponding to the signal applied on analog input pin IN4.
OUT4A/4B output digital data corresponding to the average of signals applied on analog
input pins IN3 and IN4.
OUT4A/4B output digital data corresponding to the average of signals applied on analog
input pins IN1, IN2, IN3, and IN4.
