1.
The current consumption through VREF is composed of two parameters:
- 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
1Msps
2.
VREF- or VDDA must be tied to ground.
3.
Guaranteed by design, not tested in production.
4.
Minimum sampling and conversion time is reached for maximum Rext = 0.5 k
.
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 tIDLE.
7.
The tIDLE maximum value is on the “Z” revision code of the device.
