1. Data guaranteed by design, not tested in production.
2. The current consumption through V
3. V
4. Minimum sampling and conversion time is reached for maximum Rext = 0.5 kΩ..
5. Value obtained for continuous conversion on fast channel.
6. The time between 2 conversions, or between ADC ON and the first conversion must be lower than t

- one constant (max 300 µA)
- one variable (max 400 µA), only during sampling time + 2 first conversion pulses.
So, peak consumption is 300+400 = 700 µA and average consumption is 300 + [(4 sampling + 2) /16] x 400 = 450 µA at
