All ADC channel specifications are guaranteed during normal MicroConverter core operation.
Apply to all ADC input channels.
Not production tested; supported by design and/or characterization of data on production release.

The input signal can be centered on any dc common-mode voltage (V
When using an external reference input pin, the internal reference must be disabled by setting the LSB in the REFCON memory mapped register to 0.
Endurance is qualified as per JEDEC Std. 22 Method A117 and measured at −40°C, +25°C, and +85°C.
Retention lifetime equivalent at junction temperature (T
Test carried out with a maximum of eight I/Os set to a low output level.
Power supply current consumption is measured in normal, pause, and sleep modes under the following conditions: normal mode = 3.6 V supply, pause mode = 3.6 V
