Hello ,I'm trying to connect Adafruit microphone using SAI of the STM32L4. This microphone uses I2S protocol, and delivers as output PCM 24 bits data,(The microphone includes Segma delta filter and a decimator which are used to convert PDM data to PCM data), over sampling rate fixed at 64 and Clock frequencies from 2.048Mhz to 4.096MHz are… (Show more)

Hello Community, Does the SAI sub-block clock source matter when it is in Synchronous Slave mode with the other sub-block? In other words, should the two sub-blocks have the same clock source? Thank you.

I want to generate simple audio waveforms and send them out through the headphone jack, preferrably using a synchronous interface such as HAL_SAI_Transmit. (I know there are better/more efficient ways to do this which don't peg the CPU, but I just want to keep it simple to start off).   Are there any good resources (especially example code!)… (Show more)

Hi     I am trying to build an announcement system using TDA7491P audio CLASS D amplifier. I am not able to figure out how to control the volume of the speakers using the amplifier.

I am trying to read back I2C registers on the TDA7419 audio processor to verify their contents.  I've try both standard I2C register reads as well as the custom method on Page 29 of the datasheet (rev7).  In all cases, a NACK is received and no data is transmitted.   Does register read-back work on the TDA7419.  If so, does anyone have an… (Show more)

Hi at all,   I wanted to order a sample product to try to build up a own bluetooth box. After I send my request, it shows your order has succesfully created but I can't see it in the order history. After I close the tab, it shows the items in the chart again.

For a new design, I need an AES/ EBU receiver IC that can accept balanced inputs. The STA120D seems fit. However I cannot find the product page on the ST website even though the IC is available on Mouser and Digikey.   May I know the status of this product and is it recommended of new designs? Is there any other alternative that I can look into?… (Show more)

I would like to use TN3050H-12GY-TR SCR at 400Hz. I am just not sure how would it be rated based on SCR controlling a pure restive load using 200Vac at 400Hz.

Hello,   Datasheet recommends connecting both MUTE and STBY pins on TDA7293 using R-C for delay to avoid pop noise. I would like to know if I can connect MUTE pin using R-C, as recommended, and connect STBY pin directly to VCC.   Thanks!!
