The STA326 datasheet (DocID11531 Rev 9) is unclear on a couple of points, so:   * Does the STA326 output power level depend on the output stage supply voltage (VCC[12][AB] on pins 4,8,11,15), or does it depend only on the digital signal chain (digital input signal and volume and effects settings) ? The output clipping level will of course… (Show more)

   Hi, I'm quite new to the STM32F4 and am currently trying very simply to play audio from a binary file flashed into memory. I'm using eclipse with the ARM tool chain and the supplied drivers. I'm getting stuck on playing a binary audio file flashed into the chip at a specific address. I've very simply based my code on some of the example files,… (Show more)

On the steval-mki138 MEMS microphones dev kit, using the STAudioHub firmware and tools, I am observing a significant time drift between 2 developments kits acquiring the same audio signal at the same time. I am now looking for ways of improving this situation. Is the STAudioHub firmware source code available somewhere? Did anybody try difference… (Show more)

Hello ,   Could you kindly recommend me any STM  kit that can be applicable for MEMS microphone ? This kit should be USB interfaced with PC, my plan is to connect it to VL812 USB 3.0 Hub Controller .   Is it possible to make PDM interface with STM kit?

We are seeing some of our opamps failing, outputting the VCC rail regardless of input!   The input signal is a BLDC fan current sense resistor and cell a is a non-inverting gain of 3x.   Our sleep circuit was implemented incorrectly, during sleep Vcc is actually 1.5V instead of 0V, can this damage this part (note: other pins should be at 0V… (Show more)

We use osxAcousticEC library on STM32F401CBY6. For only one MCU, we can use OSX LicenseWizard to get license and this function is ok. But we are going to mass production, could you tell me how to batch obtain license? Thanks.

Hi   Looking at the TDA7492P, but this seems to apply to the TDA749xxx devices as I checked those data sheets too.   SVCC (35) and SVSS (36). Is the schematic correct? Do I simply connect the two with a cap, but neither to power or ground?   PGND (18). Should this be connected to ground? Schematic shows it is bypassed to VDDPW(19), but… (Show more)

Hi all, I would need courtesy if anyone knows this component, and what happens if I replace it, is part of the PSU of a Pink Triangle LPT that fused, I can not do all the possible searches to find it. This is the acronym M706Bl or 88932, I think it's a voltage reference but I'm not sure. Thanks to everyone who wants to give me some help. Kind… (Show more)
