1.
The current consumption through
- one constant (max 300 µA)
V_REF
is
composed
of
two
parameters:
- 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
1Msps
2. V_REF- or V_DDA must be tied to ground.
3. Guaranteed by design.
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_IDLE.
7. The t_IDLE maximum value is ∞on the “Z” revision code of the device.
