Hello,A PDSO14 type component with the marking EZ9Q706 (ST Microelectronics) is on an electronic board. Would it be possible to have the datasheet of this components?Thanks.

i have set enables 1,2,3 and 4 as 1100 which is address 2 , but for some reason the speaker is not open and voltage is not passing through it which means i cant move on and give orders through i2c registers, can you please explain what the reason might be?

I have several "mystery" failures of STN1HN60 in one of our commercial product ranges. There is no easy design fault or abnormal condition that that we can find.I would like to analyze ththe failures by observing the internals of the faulty part. Some other manufacturers have application notes with images of the different failures but they do not seem to apply to the Supermesh type parts. Can ST please provide this for the Supermesh type FET? If not, can SST help in any other way please?

Needed Detailed Thermal Model for TDA7803A which includes Die, Solder balls etc., and their material properties for thermal simulation

Hi, I recovered a program and I would like to use but I do not understand very well. Could you give me some info. Thank you for your helps Regards

Is it possible to operate 2 x TS4984 amplifier as a PBTL only using the Left channel from each product. (Both products share the same power domain)We have prototyped a small interface consisting of 4 x 100uF non-polarized capacitors to mix the differential outputs to a single output channel which then connects to the load (8 Ohm speaker). Seems to work well, just need confirmation this approach will operate safely, not harming the amplifiers I.e audio signals not the same/synced.Product (A) will be playing music, whilst Product (B) will be mixing in a secondary audio signal (i.e Alert Beeps, Speech).Kind regards,Daniel

Hello, I would like to know how to communicate a CODEC SGTL 5000 with STM32 ? Do you know where I can find the the library (.C and .h) of this component ? Thank you for your helps. Regards 

I have an application where I'm using a 0.001 ohm sense resistor and the TS2010H Current Sense Amplifier with a 5V supply and VREF1/VREF2 tied so that the reference is 2.5V. The output goes through an RC circuit into an A/D converter input to a micro.The circuit is monitoring an AC current waveform through the sense resistor. Nothing fancy. With any amount of amperage flowing through the sense resistor, I have verified that the sense resistor is generating the correct voltage (Vsense = Isense x 0.001), The issue is the TSC2010 output is 22 times greater, not 20 times greater. This is of course 10% error instead of the specified 0.3%, and it is causing big problems to the device. I've checked every one of the error contributors detailed in Section 5.6 of the specification (pages 30-32), but none of them are the cause. It just seems the gain is off by way more than it should be. What could I possibly be doing wrong? Thank you for any ideas.UPD

Good afternoon....I am looking into using an STA540 in a power amp design for a single supply 4 ohm speaker. Other than the datasheet there seems to be no reference design material on how to use this chip. I have found Sparkfun has a reference design and am trying to leverage that. I would like to know however (from audio expertise) on whether or not I need to place a zobel network on the output? whether I need to place a parallel RL in series with the load? and finally if so what are suggestions for values AND power handling size for the resistors??Thank you

Hello, I send you this message to ask you to provide me, if possible, the information below- RoHS II Status : Yes, with exemption, No- J-STD-020 Moisture Sensitivity Level Rating (MSL)- Termination Plating Finish- Quantity of parts in a packaging ( Reel )For the following manufacturer references:- TSB7192AISTAwaiting your response, please accept, Sir, my sincere greetings. Thank you very much in advance. Best Regards,

STuW81300I designed a device with STuW81300. PLL locked. I received output power like in the datasheet. Okay. But when I measured the output signal, I saw a lot of spurs. I don't know how to improve my signal. Do you give me support about this spur? @Peter BENSCH I need help. I shared two pictures. Please don't care power level in the pictures. Please, take care of the spurs level. How can I make a pure signal without spur?My loop filter is the same as the datasheet.Thank you in advance.Best Regards,Yigit.

Sometime ago, I've built-up a simple single-sided test brd where I could plug-in a TDA72xx series family power amp without a pre-amp. It works supremely. I advanced the design to include a front-end with or without a pre-amp. Under the same design, same configuration, following the same app note to the tee, the TDA7269A amp attempts to start up and immediately shuts down.If anyone has any suggestions to try, I would be happy to try them.Thanks,Dave

I am using the STuW81300 as LO generator to generate 12GHz LO. Although I am able to get the frequency out correctly and the PLL is also locking the output power of the signal us at -39dBm (probing) where ideally it should be giving close to -4dBm. The is some difference in the LOOP FILTER section of my schematic compared to the EVB schematic. Other than this I cannot understand why it is not giving the said output power. I seriously doubt that this could be the cause for this as the PLL is locking and I am able to generate the required frequency.I am also attaching the Schematic for reference as well as the register initialisation mapping is also given below.Regist
