i want to convert (0mv - 1000mv AC)signal in to precise dc voltage for input to ADC of STM32 micro-controller for measure ac mains voltage suggest me any ic (single power supply +5V dc) or circuit diagram
Half wave or full wave bridge rectifier, filter caps and a conversion factor to calculate the peak, peak-to-peak or RMS value of the original AC voltage from the resulting DC voltage. Stretch your search engine muscles. The answers are out there.
