Some time ago I had to connect some analog signal source to the STM32 A/D converter. Amplitude of the signal was specified in wide range from 0.5V to 9V and the frequency was in range of 1kHz to 10kHz. These values of the signal parameters are common for some piezoelectric vibration sensors.
After that project I decided to design the modular system for the signal conditioning.
My aim is to make simple and reliable modules of the signal filters and amplifiers to use with the stand-alone or build-in A/D converters.
In this project I will publish information about the RTA-500 design, parameters and examples of usage.
