what is the output impedance of the output buffer inside the AD8436 RMS->DC device for frequencies around 100 Hz ?
I tried this out on bench and you should be looking at about 72ohms of output impedance at 100Hz. I have also verified this with our expert for the AD8436.
I am curious to know what your application is. Would this be for a commercial application? We are always interested to know what our customers are getting into.
thank you for the reply and for taking trouble of measuring the value! This explains my observations. The part is used in a scientific lab to measure conductivity in liquids.
