I am using stm32g491ret6 for generating sin, triangle, sawtooth and square waveforms using LUTs.The frequency of the waveforms can be changed by changing the timer auto-reload register value. How I can change the auto-reload register) value programma...
Hi, I have a problem with audio acquisition using PDM microphones. After using PDM_Filter, single peaks of high amplitude appear in the data in addition to the correct readings. I am using 4 microphones MP34DT01-M, STM32H743 and SAI interface. I take...
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...
