Conversion characteristics vary with F
QADC pins as GPIO functions during conversions may result in degraded results. Best QADC conversion accuracy is
achieved at a frequency of 2 MHz.
At V
Accuracy tested and guaranteed at V
Current Coupling Ratio, K, is defined as the ratio of the output current, I
injection current, I
input voltage error on the channel under test is calculated as Verr = I
Performance expected with production silicon.
