How to fix Noise issues in PDM to PCM Conversion?
Hey,We are implementing digital microphone interfacing using ST's IMP34DT05TR microphones connected to the STM32G473VET6 microcontroller through the PDM interface, following guidelines from the application note AN5027, specifically Example 3.The conf...
TDA7294 Bridge application
Hello everyone. Regarding an amplifier with two TDA7294 in bridge configuration, looking at the diagram, on IC 1 at pin 3, there is a high pass filter formed by the 0.56uF capacitor C1 and the 22K Ohm resistor. The cutoff frequency is 12,91 Hz. I wou...
POWER IC FDA901 DC diag open circuit
what is the block meaning between 22.2Ω to 36Ω?what if the detected resistance value is 30Ω, what will be written in the registor and what is the result will be reported?
TDA7294
Hi, no sound at all from one of the studio monitors that each use 2 TDA7294 IC’s. Pulled out PCB from both monitors. The board that functions normal, the TDA7294s get warm after a minute or so, that’s a good sign, and yes this one works fine. The oth...
FDA903S detailed user manual
I wolud like to use a Class-D Audio Power Amplifier FDA903S with STM32F103RC microcontroller, but I can not find a detailed user manual of FDA903S. On the product page is only a short 15 pages description.Where can I find the details from this amplif...
FDA903 I2C documentation
Can you get a detailed document on I2C in FDA903Q?Best regards, thank you
TDA7492E - analog input section.
Hello,I have two questions regarding TDA7492E amp. 1. What is the common voltage for audio inputs? 2. What is the maximum usable voltage on audio inputs? I would like to increase amplitude by op-amps, not the amp gain. Thank you and best regards,Prze...
