 		 #80357 - RE: Hey, 8 bits
Responding to: ???'s previous message
What am I missing here ? Why not just use a bipolar input ADC (or offset the input to the ADC you have) and do the whole RMS thing on the fly in software ? Are you using the mean of the output of the precision rectifier to drive some other control loop or something ?
