hi, boys.I bought 100 TDA7297 and ran only 2. I wonder if there might be fakes in the market for this Amp Model , or if there is another version that works with other than the proposed schematic datasheet . Someone has something similar happened ?. The number of the batch of every hundred devices is : SINGAPORE W88030938 . Thanks for the help and comments.

Hi Salazar,
TDA7297 was very mature class AB device when ST was still named as SGS-Thomson. according to your description , if your application circuitry (both of schematic and PCB layout) had been proven with TDA7297 in the past , you should get some device that was not ST original . to clarify it , it's better to contact with your dealer. thanks YT2016-01-08 04:24 PM
