i want to calculate RMS value of Sinusoidal 50Hz waveform. so, i thought to use AD737 IC. but in the datasheet i have used evaluation board circuit . it's not working and also i used figure29 of datasheet both are not working.and the circuit pictures are attached.
so, i'm in great need of this. and i want to make use 1V RMS measurement.
1V RMS mentioned in the datasheet means either peak-peak or RMS value.
please, suggest the circuit to be used which will measure 1V rms , 50Hz sinewave.
i'm not getting any application circuit for AD737which is working. please help me.
Thanks & Regards
