2: The A/D conversion result never decreases with an increase in the Input Voltage, and has no missing codes.
3: For V
4: Maximum allowed impedance for analog voltage source is 10 kΩ. This requires higher acquisition times.
ADRES
2: This is a minimal RC delay (typically 100 ns), which also disconnects the holding capacitor from the analog input.
