Not getting desired frequency from DAC output pin
Hi, am having an STM32F303K8 and using its DAC to generate a sinewave of a given frequency. Am using TIM6 update event to effect the results on the DAC periphery. AM running the APB1 bus at 16MHz, and my sinewave table has 256 samples. I set my presc...
Tda7265 mute pin problem(play dont work)
I have a problem with the following:I built the single power supply circuit which mentioned in the datasheet (second picture). I use 20.5V Vs and 2x15W 8ohm speaker for output.I measured the Mute pin(5) with multimeter and always showed me 14V.It is ...
How to transmit Audio using UART.
Hi,I'm using STM32WB5MM-DK board interfaced with SPH0645LM4H I2S mic for capturing audio. I also connected a playback speaker with the setup I have mentioned. I also configured UART for transmitting the PCM data from STM32WB5MM-DK to PC. When I trans...
Resolved! TS9222 i
Hi, Below is the design1) input voltage at inverting side is 8V with the 4.7k series connecting to inv terminal2) voltage at non inverting terminal is fixed at 3.5V.3) the difference between inputs is greater than 1V(Vid=1V). 4) My question is whethe...

Resolved! DD-out pin on the TDA7376B
Hello everyone.what the DD-out pint is used for on the TDA7376B?Does it cancel out the channel when it detect clipping on that channel?
Resolved! Need datasheet or equivalent for this Z010 Diode
Good morning, for a repair I am looking for a data sheet for this TVS diode or a recommendation for the replacement. Many Thanks.
TDA7803A: What's the meaning of the Unit 'Vp' in Voltage Gain section on the datasheet
In TDA7801 datasheet, voltage gain marked as db(Vp), if the full scale output level of internal dac is 2vrms, with a gain at 16db, the amplifier full scale at 12.7vrms(if no rail limit), Is that correct?But in TDA7803A/TDA7808 datasheet, voltage gai...
