I am currently using the AD9957, works pretty fine.
Nevertheless I noticed the current drawn by PIN3 (1V8 AVDD for PLL) is around 27 mA, according to the component DS (rev. D, pp46/64) it should be closer to 7 mA.
This could be an issue for our design, hence my questions :
- Is this behaviour normal ?
- What is the actual maximum current drawn by PIN3 of the chip ?
Thank you in advance for your quick reply.
