i bought this chip for our lab. we need to measure the current rms value of a certian device in our experiment.
we plan to use CT and measure the rms voltage on a shunt resistor.
i tried to simulated the DVM circuit from the data.
but when i probe the output pin i get increasing of the voltage...
i attached picture of the circuit and the file of the simulation.
please help me with that...
thanks and best wishes,
I came to this post because the examples on both the datasheet and applications notes for the AD737 did not work.
ScottH is right with his circuit proposal. It provides a negative DC signal on the AD737 Output (Pin 6) that is proportional to the RMS value of the input signal.
