SAR8 ADC DC Specifications

The following table lists the guaranteed maximum and minimum specifications for the voltage and temperature ranges: 4.75V to 5.25V and -40°C ≤ TA ≤ 85°C, or 3.0V to 3.6V and -40°C ≤ TA ≤ 85°C, respectively. Typical parameters apply to 5V and 3.3V at 25°C and are for design guidance only.

Notes

12.SAR converters require a stable input voltage during the sampling period. If the voltage into the SAR8 changes by more than 1 LSB during the sampling period then the accuracy specifications may not be met
