Notes:
1. Requires enabling Analog Calibration using SmartGen Analog System Builder. For further details, refer to the
2. Direct ADC mode using an external VAREF of 2.56V±4.6mV, without Analog Calibration macro.
3. For input greater than 2.56 V, the ADC output will saturate. A higher VAREF or prescaler usage is recommended.

Examples
Calculating Accuracy for an Uncalibrated Analog Channel
For a given prescaler range,
where
Formula
Channel Output offset in V = Channel Output offset in LSBs x Equivalent voltage per LSB
Channel Gain Factor = 1+ (% Channel Gain / 100)
Example
Input Voltage = 5 V
Chosen Prescaler range = 8 V range
Refer to
Max. Output Voltage = (Max Positive output offset) + (Input Voltage x Max Gain Factor)
Max. Positive output offset = (8 LSB) x (8mV per LSB in 10-bit mode)
Max. Positive output offset = 64 mV
Max. Gain = 1 + (2/100)
Max. Gain = 1.02
Max. Output Voltage = (64 mV) + (5 V x 1.02)
Max. Output Voltage = 5.164 V
