Hello -We are having issues with EMC compliance with the TDA7492E. We have broadband radiated EMI between 100MHz and 200MHz that is above the limits. I've included a screenshot of the testing lab's report with the radiation. I've attached our schemat...
Hello, I have a guitar amp Laney LA65C where the output amp is faulty, it consists of a TDA7294 IC, I put in a new TDA7294 but it exploded as soon as the power was turned on. I checked the input voltage and it is correct 26 volts, what could cause it...
I am wondering why they use a thermistor to monitor temperature when they have a reference detector?https://www.st.com/resource/en/application_note/an5571-signal-conditioning-for-ndir-sensor-stmicroelectronics.pdf
We use the RHF1401 in a space application. In front of the RHF1401 we have a single to differential buffer, which is susceptible for radiation transients. So it can occur, that the RHF1401 receives a transient with -1.3V to 5.55V at is inputs. The tr...
Do ST has spice model for opamp ? Especially TL062
我现在想用stm32F407系列的spi口来采集mp34dt05的PDM麦克风的数据，但是我发现我采集到的pdm数据流基本上不会因为我的环境变化而产生任何变化。你能详细告诉我spi是怎样的吗？要接收mp34dt05的数据，麦克风芯片mp34dt05有驱动文件吗？如果有的话可以发给我吗？感谢您的关注。Translated from Chinese to English: I am now trying to use the spi port of the stm32F407 series to c...
Hello, I am attempting to identify a component from a switch mode power supply out of a audio preamp.I am 90% confident it is a zener diode, but after that I am at a loss. Markings (cathode band on left):(ST) 98ZKW *not sure if there is a space betw...
请问如何购买STA309A评估板？你们提供技术文档支持吗？Translation to EN: How can I buy the STA309A evaluation board? Do you provide technical documentation support?
Hi Team, @Peter BENSCH I want to process PWM HART signals of 1.2 KHz/2.2KHz. Will the op-amp TSX631A be suitable for this application which is having a bandwidth of 200 KHz? Regards,Sreejith R Nair
Hi,@Peter BENSCH In the datasheet of ST LMV321ILT op-amp, it is stated that minimum voltage supply span is 2.7V and maximum supply span is 6V. Can you suggest whether LMV321ILT can be used with 3.3V or an alternate that is both pin to pin and 3.3V co...
