First steps with STUW813000

I am starting my first project with the STUW813000. I don't seem to find a clear answer to the following 2 questions:My power consumption is on the level of 6-7mA on the supply line of 5.5V. No ref signal yet present, HW_PD@GND, PD_RF1@GND, PD_RF2@3....

We have manufactured a circuit for the STuW81300. We have conected it to an Arduino We are not able to discriminate if the problem comes from the circuit or from the code.

Dear Friends. We have manufactured a circuit for the STuW81300. We have conected it to an Arduino Due. But, we are not able to code the STuW81300 and we are not able to discriminate if the problem comes from the circuit or from the code.We want to re...

RHF200 Simulation Problem

Hi. I am simulating rhf200 using TINA Tool. The data sheet shows that the input voltage range is above 1.3v, so the input applies a voltage of 1.6v and the output common mode applies a voltage of 0.8v. Then, load resistance was attached to the rhf200...

I am currently designing with the LM119 dual comparator. While simulating my designs i noticed that the Spice model provided by ST for this IC is incorrect. The Gnd pin is missing and it completely changes its behavior. Is there any way to fix the model?

Hi, Please tell me the upper compatible model of the TDA7265B, for upgrading the existing amplifier.

1N5711 knockoff ?

I recently bought a couple of 'STM' 1N5711 diodes via EBay and measured/compared them to the 'STM' 1N5711 I've bought via Mouser.The forward voltages differed quite a bit:Mouser 1N5177 -> 353mV @ 1mA EBay 1N5177 -> 242mV @ 1mAMouser 1N5177 -> 270m...

Good afternoon, I have a device with reference 324 STI MZL8909 and another with reference G002204, the first works well but the second doesn't work. Which is the diference? Both are like LM324DT?

I attach images.

Hi All, Does anyone have the AWR model for PD55003L-E Please share them with me. Thanks,

Suggest me that how I feed audio signal to MCU ?
