1. The current consumption through VREF is composed of two parameters:
2. V
3. V
4. Minimum sampling and conversion time is reached for maximum Rext = 0.5 k
5. 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 ìA and average consumption is 300 + [(4 sampling + 2) /16] x 400
= 450 µA at 1Msps
