Analog Discovery 2 high temperature

[Austin Gosling]

I've connected my AD2 to an external 5VDC power supply, and it is drawing about 1.1A while disconnected from any external circuits. This cured the overcurrent status and low USB voltage (~4.0) I was having while running only off USB.

However, WaveForms status is now HT (high temperature), running about 71 - 72 degC.

Is this expected? At what temperature should I be concerned with damaging it?

Update - after being connected to AUX 5VDC for about an hour, the temperature went up to 88 degC and it disconnected from WaveForms.

After letting it cool down, I reconnected via USB only - no AUX supply - and it is back to the state I originally got it in (see other post). It will only connect in mode 4 (no analog).

It now tells me to connect the AUX power, but when I do, the current shoots up to 1.3A.

I suspect something is deeply wrong with this unit.

Any ideas?

Hi @Austin Gosling,

I'm not certain on how hot the AD2 usually gets, but that does seem high to me. @attila, have you seen something like this for the AD2?

Thanks,
JColvin

Well, I have requested a replacement from support by email, but have had no reply yet. I figured the holiday season might slow things down. I don't know the procedure. I purchased it from mouser.de in Germany.
