ADC Internal Resource Measurements

9 Input must be current limited to the value specified. To determine the value of the required current-limiting resistor, calculate

resistance values using VPOSCLAMP =VDDA + 0.5 V and VNEGCLAMP = –0.3 V, then use the larger of the calculated values.

10 Condition applies to two adjacent pins at injection limits.

11 Performance expected with production silicon.

12 All channels have same 10 k

Ω <Rs<100kΩ Channel under test has Rs = 10 kΩ, I

INJ=IINJMAX,IINJMIN.

13 The TUE specification is always less than the sum of the INL, DNL, offset, and gain errors due to cancelling errors.

14 TUE does not apply to differential conversions.
