Note 1: Stresses beyond those listed under Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to any Absolute
Maximum Rating condition for extended periods may affect device
reliability and lifetime.
Note 2: The ADC specifications are guaranteed by the Total Measurement
Error (V ERR ) specification.
Note 3: Due to the contact resistance of the production tester, this
specification is tested to relaxed limits. The 20Ω limit is guaranteed by
design.
Note 4: V CELL refers to the voltage applied across the following pin
combinations: Cn to Cn-1 for n = 2 to 12, C1 to V – . V TEMP refers to the
voltage applied from V TEMP1 or V TEMP2 to V – .
Note 5: These absolute maximum ratings apply provided that the voltage
between inputs do not exceed their absolute maximum ratings.
