Hello, We are trying to get information regarding your PCN CRP/21/11964, we are having this inconvenient since July 2021. Do you have a qualification to share with our automotive customers ?

comparison between old location vs new location (same tooling? same process?)Your PCN CRP/21/11964 states dates from 2020 (see enclosed) ..... is it a mistake ?Please provide us information regarding the dates LTB and LTS.Please advise regarding data...

TDA7293/94 on single supply voltage?

Is it possible to run e.g. 2 x TDA7293 in bridge configuration on a 24 VDC single supply voltage as it can be done on many other ICs by feeding the non invertig input with 1/2 supply voltage ?

Resolved! TDA7376B 2 channel power amplifier How is the internal Vref controlled? Is it a fixed, constant voltage? or is it a scaled fraction of the main power supply Vdc?

If it is a scaled fraction then how does it get filtered from transient changes of the Vdc supply?If it is a fixed constant voltage then the outputs will be biased at that same voltage and peak output audio will be clipped non-symmetrical. For examp...

I have configured the code for Analog Microphone with UART DMA in STEVAL -MKSBOX1V1. Anyone please guide how to verify the data. (When to start audio using ADc interrupt and play any audio ). Right now I have done as continuous conversion and circular..

I need to capture as soon as Audio is played. In real time without user intervention how shall we start the ADc conversion and how to validate the data is converted properly. Audio is w,r,t to sampling rate , if so I am using 8 KHz with DMA . If I pl...

I'm trying to work with STAPI003 audio amplifier, in the datasheet it says that it 4 x 52 W/4 Ω max, but i am not able to get more than 32 watt at 4 ohm. How can i achieve above 32 watt, is it possible to bridge the output?

HardFault_Handler upon updating variables inside DMA Callback

Hi,I am currently implementing a guitar effects pedal using the STM32F446RE and the PCM3060 as my CODEC.I have gotten everything to work, except when I try to adjust the following parameters cf0_lim = (int)(time*l_CB0); cf1_lim = (int)(time*l_CB1); c...

I what to use senortile.Box and capture the voice in ADC. I have gone thro the schematics. is it ok to configure only ADC or we need other parameters like OPAMP Setting and DACOUT . I have seen these in the Schematics.

In some training session they are using ADC calibration in the code , whether it is required ?Any sample reference code for Analog microphone step by step guide or Video. I have seen many Youtube Videos.

Please advise what is the difference between the STA516B and STA516BETR? We only find the datasheet STA516BE and cannot find the STA516BETR.

Mono audio source in Flash

I want to play an audio clip over i2s from Flash memory. My application is mono and a mono source will fit in flash, but not stereo, it is too big.The HAL i2s interface does not appear to offer a mechanism to duplicate mono source bytes (16b) onto th...

Resolved! What is the typical input capacitance for STM6524 SR0 and SR1 inputs?

I have my I2C bus connected to an STM6524, and I see that my rising edges are slowed down a bit more than expected. What is the input capacitance of these inputs? Thank you!
