1. The Vref+ input can be grounded iif neither the ADC nor the DAC are used (this allows to shut down an
2. The current consumption through VREF is composed of two parameters:
3. V
4. V
5. Minimum sampling and conversion time is reached for maximum Rext = 0.5 kΩ.
6. For 1 Msps, maximum Rext is 0.5 k

- 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
