Posted on July 20, 2017 at 14:13Hello 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.
Posted on September 21, 2017 at 00:41Greetings I'm currently looking for a spice model of the L7805CV 5V Regulator for my design simulation , I've looked on the product page and keep seem to find anything . Is there anyone who can point me in the ri...
Posted on September 06, 2017 at 19:49Hi 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.
Posted on April 27, 2017 at 21:22I 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 case...
Posted on February 22, 2017 at 20:34Hi 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 ...
Posted on August 28, 2017 at 06:46For 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...
Posted on August 22, 2017 at 16:39I 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.#tn3050h-12gy-tr #400hz #scr
Posted on July 27, 2017 at 13:14Hello,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 t...
Posted on July 21, 2017 at 15:26Hi,I'm using STA309A, and wondering the differnces between DDX damped ternary and binary PWM output, since there is no waveform examples in the DS. Anyone knows this? thanks a lot~Li dongsheng.
Posted on July 18, 2017 at 17:11#Help.!!! The TDA7491LP mute pin is the input port. I connected the 3.3V pullup resistor 33K resistor to the power supply, and the mute pin keeps the state of LOW state .... What is the cause? So there is no sound. . ...
