Description
Input configuration
Front and rear selector
The input stage (Main source and 2
application. There are 7 different configurations which provide different input structure and
different number of input sources as shown below.

QD = Quasi-Differential, SE = Single-ended input, FD = Full Differential, MD = mono
Differential
The configuration of the input stage is controlled by ‘Input Configuration’ bits in I
table (Byte0 Bit5~Bit7). The table below shows the configuration of input pins in different
configurations.
