NOTES:
1. Tested at 12.5-MHz ADCCLK
2. If SYSCLKOUT
≤ 25 MHz, ADC clock ≤ SYSCLKOUT/2
3. The INL degrades for frequencies beyond 18.75 MHz 25 MHz. Applications that require these sampling rates should use a
20K-resistor as bias resistor on the ADCRESEXT pin. This improves overall linearity and typical current drawn by the ADC will
be a few mA more than 24.9 k
bias. The ADC module in C281x devices can operate at 24.9k bias on ADCRESEXT pin for the
full range 125MHz
4. 1 LSB has the weighted value of 3.0/4096 = 0.732 mV.
5. A single internal band gap reference (
±5% accuracy) sources both ADCREFP and ADCREFM signals, and hence, these voltages
track together. The ADC converter uses the difference between these two as its reference. The total gain error will be the
combination of the gain error shown here and the voltage reference accuracy (ADCREFP ADCREFM). A software-based
calibration procedure is recommended for better accuracy. See F2812 ADC Calibration Application Note (literature number
SPRA989) and Section 5.2, Documentation Support, for relevant documents.
6. In this mode, the accuracy of external reference is critical for overall gain. The voltage difference (ADCREFPADCREFM) will
determine the overall accuracy.
7. Voltages above VDDA + 0.3 V or below VSS 0.3 V applied to an analog input pin may temporarily affect the conversion of another
pin. To avoid this, the analog inputs should be kept within these limits.
