TSU101 Op. Amp. operation problem

Hi All, I have used ​TSU101 op. amp.as a comparator in my design. Output of opamp is used to drive relay through mosfet. My problem is when i connect power supply to my board o/p of comparator change for fraction of second and again work correctly as...

STA350bW output line unbalanced

HelloI have an audio card based on the STA 350BWit has 4 amplified mono outputs.I would like to modify it to obtain 4 unbalanced mono line outputsthanks !!

Is there anywhere to be found on ST's website, the reliability Data of ST Parts? For instance the FIT value of a part, for MTTF calculation.

About the receiver suitable to STEVAL-IME013V1

I'm using STEVAL-IME013V1 ultrasound pulser IC evaluation board. I'm using the board as 8 channel pulser for ultrasound sensor and now I want the board to receive the reflected waves. I made the phased array program and use beam forming, so I want to...

TDA7440 ACK problem

I made the circuit whose diagram is given on page 4 of the document in the link.I am applying 9.1v to the circuit.I can't get acknowledge to 0x88 address that I sent after start.https://www.st.com/resource/en/datasheet/tda7440.pdfI'm sure about the s...

What is the difference between TS914AIYDT and TS914AIDT?

There was a description about screening in the datasheet.Are there any differences in electrical characteristics and materials?Is it the same IC with only a difference in test coverage?

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...
