Dear ST support teamAs shown in the diagram, I use a current transformer (PT1) and an amplifier to measure AC voltage:When U1A is LM258DR of TI, the system works perfectly well. After replacing U1A with LM258DT of ST, the waveform measured by the osc...
The M41T62 driver provided in STSW-M41T62 appears to have an error related to calibration of positive adjustments. Refer to the code below from line 750 of M41T62.cThe sign parameter is 0 or 1. To program the M41T62 for positive compensation requires...
I have just bought the STEVAL-IME009V1. It comes with a factory settings DFU file and DfuSe evaluation tool (STSW-STM32080).It generates and extracts hex files, but how can I edit those files to create impluses and burst pulses with specific frequenc...
Hello Support,I have application in wjhich i have to sense current for negative supply. specifications are as below.Negative supply voltage range( at RS- pin) : -5 V to -2 VCurrent range that needs to be sensed: 0.1 uA to 20uAThe output of OPAMP need...
Hello ST experts, I am working on TDA7801 chip and I didn't find an explained way for programming it or even a simple code. To be specific, I can't read or write data to chip registers through I2C.!! Can you help?.best regards Hossam
Dear ST support team,Good morning,I want to find alternative part for TSZ122IST . we check the data sheet and find out the TSZ122IYDT. But we didn't saw the difference between them.Please support to explain this case Thank and Best Regard,Danny,
HiThe Android All-in-One product I'm using has an amplifier chip called TDA7838 built-in. I would like to know the difference between the TDA7850 amplifier chip. I would also like to receive a datasheet for the TDA7838. I look forward to your answer.
Hello.I'm trying to import the SMR module of the X-CUBE-AUDIO package in one of the projects I am working on. I wish to know the sound pressure level in dB on my microphones.My application generates a PCM buffer filled this way: 32 samples in 16-bit ...
