AC CHARACTERISTICS
Standard Operating Conditions: 3.3V and 5.0V (±10%)
(unless otherwise stated)
Operating temperature -40°C ≤ TA ≤ +85°C for Industrial
-40°C ≤ T
A ≤ +125°C for Extended
Param
No.
Symbol Characteristic Min. Typ Max. Units Conditions
Note 1: Because the sample caps will eventually lose charge, clock rates below 10 kHz can affect linearity
performance, especially at elevated temperatures.
2: The A/D conversion result never decreases with an increase in the input voltage, and has no missing
codes.
