Hi,
The I_AVDD is 225µA typ for AVDD=5V according to the datasheet. I assume something similar value applies to +/-2.5V analog supply. The chip seems to consume a way more current during startup.
Can you give a maximum specification that covers the startup too?
What about any timing / slew rate / monotonicity constrains for reaching the recommended supply voltage range (+2.25V)?
Thanks,
Tamas
