Where can I buy TA2022's with confidence?
I am servicing an italian brand called DBTechnologies, I have ordered to my representative some pieces of TA2022's but without any logical reason, they have burnt instantaneously.
There is no point of thinking about a problem on the design, because I have only replaced damaged parts. The voltages are OK, there are no leaky diodes and, and finally, the output is perfect, I mean, no shortcircuit.
At the end, I have an idea flying around and is the possibility of counterfeit parts. Does any of you ever experienced something similar?, I am very worried because I try to buy them at trustable component sellers but none of them has this part available. I also have another question in mind, if Tripath is closed and Cirrus is not manufacturing this part where are all this TA's coming from?
Hoping to get some light at the end of the tunnel, thank you for clearing my clouds.
