PARAMETER MIN TYP MAX UNIT

ADC clock(2) 1 kHz
25 MHz
ACCURACY
INL (Integral nonlinearity)(3) 1–18.75 MHz ADC clock ±1.5 LSB
DNL (Differential nonlinearity)(3) 1–18.75 MHz ADC clock ±1 LSB
Offset error(4) –80 80 LSB
Overall gain error with internal reference(5) –200 200 LSB

ADCLO –5 0 5 mV
Input capacitance 10 pF
Input leakage current 3 ±5 µA
INTERNAL VOLTAGE REFERENCE(5)
Accuracy, ADCVREFP 1.9 2 2.1 V
Accuracy, ADCVREFM 0.95 1 1.05 V
Voltage difference, ADCREFP – ADCREFM 1 V
Temperature coefficient 50 PPM/°C
Reference noise 100 µV
EXTERNAL VOLTAGE REFERENCE(6)
Accuracy, ADCVREFP 1.9 2 2.1 V
Accuracy, ADCVREFM 0.95 1 1.05 V
Input voltage difference, ADCREFP – ADCREFM 0.99 1 1.01 V
(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-kΩ bias.
(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 the F2810, F2811, and F2812 ADC Calibration Application Report and Section 8.4 for relevant documents.
(6) In this mode, the accuracy of external reference is critical for overall gain. The voltage difference (ADCREFP – ADCREFM) 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.
