The AD737 data Sheet mentions that the two 8k resistors inside the AD737 can vary from 6.4k to 9.6k.
What I couldn't seem to find in the data sheet is how well matched they are to each other.
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…
I didn't choose any yet. I want to grasp what's going on before ...
But if it makes it easier, let's say I'll go for the AD737 http://www.analog.com/en/products/linear-products/rms-to-dc-converters/ad737.html
I have a small question about AD737.
This is my first time to use this device.
So I just wondered if there are any lmitations in case the input signal is a low frequency such…
It seems that our measurement and the contents of the data sheet are not in agreement.
If you may notice, please let me know.
VR=200ohm is used for Fig.30 in the data sheet (page16)
What kind of formula is the scale corresponding…
