<br>
looking for AD633 to a reasonable price. Ordered a few in<br>
China/ALI-Express in SOP-8 for 3€ each. Same as others I tested last<br>
year; don't work and drive hot after a few seconds. My test circuit is<br>
fine and works with AD633 bought for 10€ each. Need it for my<br>
Frequency-Shifter.<br>
<br>
Any idea?<br>
