Posted on June 24, 2017 at 15:24The 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...
Posted on June 13, 2017 at 16:45On 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 lo...
Posted on June 09, 2017 at 05:47We 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 in...
Posted on June 02, 2017 at 08:40Hello ,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...
Posted on May 24, 2017 at 10:06We 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? Th...
Posted on May 26, 2017 at 23:10HiLooking 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 p...

Posted on May 15, 2017 at 09:10I am having problems, with a TDA7491HV design (taken directly from the http://www.st.com/resource/en/datasheet/tda7491hv.pdf - Figure 50) and although it is working, the output inductors are getting very hot. Hot means...
