I need to measure a signal with very low power, the signal can range anywhere between -1 and +10 Volts but i only need the 0 to 3volts for my ADC input(my battery is also 3V). is there an opamp that fits my requirements that is less than 50uA?
I use an opamp to amplify my signal for the internal interrupt of my MCU, but after i this i also need to measure the input signal of the opamp(V+) with an ADC to measure weight. I need to know if there will be any significant changes made to the sig...
Hello everyone,I'm trying to build a system where I could read an analog signal and save it into an SD CARD. Besides this, I need to process the signal to activate, or not, the ACC reader for a few seconds.To save the values, I decided to use two buf...

I'm trying to run Audio_GrEq Audio Graphical Equalizer on the stm32f407vet6 microcontroller. The source of the input sound is i2s2, the output sound is i2s3. The SGTL5000 codec is connected to i2s2 and is configured to operate at a frequency of 48 kH...
Hey guys, I am using a STM32 nucleo f446re board and I have a waveshare sound sensor v2 that I want to use. So basically just want to record audio and store it on an SD card. I want to sample audio at 44100 Hz using 8 bits, should I use a timer to ge...
would you please help me identify this smd component? it is used in a smps circuit.
for reading micro sd audio data (SPI), I need to choose a Audio IC with Vol +, Vol-, next and pre funtion. Anyone How has expereince with that?Thank you
