Analog Input Data

This section describes the correspondence between input analog signals and analog input data.
The graph shows that a voltage between -10 to 10 V is converted to data between 80D2 and 7F2E
hex (-32,558 to 32,558).
When a negative voltage is input, it is expressed as the two's complement (hexadecimal).
-10.064 V -10 V
Analog input data is stored in the upper 16 bits of the following register.
To use a register value, divide it by 2
Input
AIN0 Gate3[i].Chan[0].ADCAmp[0] [31:16]
AIN1 Gate3[i].Chan[0].ADCAmp[1] [31:16]
AIN2 Gate3[i].Chan[0].ADCAmp[2] [31:16]
AIN3 Gate3[i].Chan[0].ADCAmp[3] [31:16]
AIN4 Gate3[i].Chan[1].ADCAmp[0] [31:16]
AIN5 Gate3[i].Chan[1].ADCAmp[1] [31:16]
AIN6 Gate3[i].Chan[1].ADCAmp[2] [31:16]
AIN7 Gate3[i].Chan[1].ADCAmp[3] [31:16]
The following table shows the conversion timing of analog input.
