The thing is I'm using a true rms to dc converter in a single supply mode, which adds an offset of 5v to the input signal (in this mode). the signal range goes from 0mV to 200mV. I recently bough a ald2321 which is a precision comparator that can read signals of 1mV+ o so I read from the data...
Hi, I've been trying to build a simple zero crossing detector with an LM741 opamp with no much success. This zero crossing must work with a period sine wave of 60hz and provide an output of 5V when the wave is positive and 0V when the wave negative. The problem is the signal that I'm going to...
