STM32L082KZ ADC load resistance

2024-07-26
I am trying to create a voltage divider to read a battery voltage of 2.5 - 3.8 V using a STM32L082KZ with a Vref of 1.8V. While calculating the required division to measure the range i wanted to include the influence the ADC measurement/loading has o...

multichannel ADC with DMA reads only 0

2020-04-22
For my project, i have to read the PA6 and PB0 pins at the same time on my STML082KZT6. These are the ADC_Inch 6 and 8. I have made a code example on STM32CubeMX for the allocations, however the only readings i get are zero.I have allocated uint32_t ...

Best Low Power buffer op amp

2020-03-10
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?

Does the non-inverting amplifier change the input voltage level?

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...

What is the time it takes for the STM32l082kb to wake up it's adc? and is a ferrite bead necessary?

2020-02-21
For my new project i have to use an ADC to measure the peak value of a pulse. This pulse wakes up the microcontroller from stop mode, and the processor has to wake up the internal adc to take the samples needed. Unfortunately i can't find the time it...
