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- must be tied to ground.

3. Minimum sampling and conversion time is reached for maximum RAIN= 0.5 kΩ..

4. Value obtained for continuous conversion on fast channel.

5. The time between 2 conversions, or between ADC ON and the first conversion must be lower than tIDLE.
