It must be guaranteed, that the input capacitance C I, , is fully loaded within this time.4TCY is 2 µs at the f OSC = 16 MHz. After the end of the sample time T S , changes of the analog inputvoltage have no effect on the conversion result.3)This parameter includes the sample time T S. 14TCY is 7 µs at f OSC = 16 MHz.4)The differencial impedance r D of the analog reference source must be less than 1 KΩ at reference supplyvoltage.Semiconductor Group 65
