Hey all,I copied this TDA7294 bridge circuit from the manuall:To this schematic: I have checked and double checked the schematic and it seems accurate to the manual's circuit. All parts are correct values to the manual's circuit. The PCB board is cor...

Posted on January 29, 2018 at 05:48I've just managed to blow up 2 TDA7498E D Class amp chips when testing the first run of 25 production boards. This is the first time we have managed to damage any chips in over a year of prototype testing.We are us...
LM324QT (QFN16 package) was used in my design as an amplifier. The design has a dual-polarity power supply with +12V, GND and -12V.I connected its exposed centre pad to GND, while connecting the VCC+ to +12V and VCC- to -12V. However, the datasheet s...
IRF520 type MOSFETs are starting to be phased out and so in all review, STP16NF06 should be a stable cross reference from what I have read, would anyone know perhaps is there a better cross for an IRF520 than the ST STP16NF06? i have ask OnSemi and t...
I'm speaking about the X-Nucle-PLM01A1 Board that uses the ST7580 IC. I would like to use this IC in a DC Bus application, not AC Line, like most of the reference design does. On page 13 of UM2189 is shown how the boards are connected. My question is...
Hello!After somet tests on Nucleo and Discovery I wan't to make some more complicated and practice project. I'm trying to make WAV file player from microSD card file.Hardware is based on STM32F103RCT6 connected with microSD card socket and DAC (PCM17...
