Freescale Semiconductor
Num
Conversion characteristics vary with F
maximum value is based on 800KS/s and the minimum value is based on 20MHz oscillator clock frequency divided by a
maximum 16 factor.
Stop mode recovery time is the time from the setting of either of the enable bits in the ADC Control Register to the time that
the ADC is ready to perform conversions.
At VRH – VRL = 5.12 V, one lsb = 1.25 mV = one count
Guaranteed 10-bit monotonicity
The absolute value of the offset error without calibration ≤ 100 counts.
The absolute value of the full scale gain error without calibration ≤ 120 counts.
Below disruptive current conditions, the channel being stressed has conversion values of 0x3FF for analog inputs greater than
V
amplifier. Other channels are not affected by non-disruptive conditions.
Exceeding limit may cause conversion error on stressed channels and on unstressed channels. Transitions within the limit do
not affect device reliability or cause permanent damage.
Input must be current limited to the value specified. To determine the value of the required current-limiting resistor, calculate
resistance values using V
Condition applies to two adjacent pads on the internal pad.
The TUE specification will always be better than the sum of the INL, DNL, offset, and gain errors due to canceling errors.
TUE does not apply to differential conversions.
Measured at 6 MHz ADC clock. TUE with a 12 MHz ADC clock is: –16 counts < TUE < 16 counts.
TUE includes all internal device error such as internal reference variation (75% Ref, 25% Ref)
Depending on the customer input impedance, the Analog Input Leakage current (DC Electrical specification 35a) may affect
the actual TUE measured on analog channels AN12, AN13, AN14, AN15.
