Notes:
1. Channel Accuracy includes prescaler and ADC accuracies. For 12-bit mode, multiply the LSB count by 4. For 8-bit
mode, divide the LSB count by 4. Overall accuracy remains the same.
2. Requires enabling Analog Calibration using SmartGen Analog System Builder. For further details, refer to the
"Temperature, Voltage, and Current Calibration in Fusion FPGAs" chapter of the Fusion FPGA Fabric User’s Guide.
3. Calibrated with two-point calibration methodology, using 20% and 80% full-scale points.
4. The lower limit of the input voltage is determined by the prescaler input offset.
