zany idea: getting more bits resolution out of the ADC

Posted on May 30, 2016 at 16:28The STM32F7 onboard DAC is only 12 bits.  I only need mono audio input.  Suppose I drive the left ADC input directly and the right from an op amp gain stage of say x16 and then combine the lowest 4 bits of R with left-...
