Note:
Input stages
The input stage (Main source and 2nd source) is configurable to adapt to different
application. There are 7 different configurations which provide different input structure and
different number of input sources as shown below.
● 4 x QD,
● 2 x QD + 3 x SE,
● 1 x QD + 5 x SE,
● 1 x QD + 3 x SE + 2 x MD,
● 3 x QD + 1 x FD,
● 3 x QD + 2 x SE,
● 1 x QD + 2 x SE + 1 x FD + 1 x MD,
● 1 x QD + 3 x SE + 1 x FD
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 I2C control
table (Byte0 Bit5~Bit7). The table blow shows the configuration of input pins in different
configurations.
