Hi friends,

I am a newbie. I am desperately trying to make AC measurements using the chip CS5460A. I could successfully communicate with CS5460A and get the readings but my problem is I do not know how to convert the internal register values to the actual voltage, current, power values of the input signal. I came across the application note an220a., it is exactly the thing I am looking for..but I am unable to understand the coding specifically the following two points.

1) When internally CS5460A registers stores measurement results in 24 bit words if we remove the last 8 bits and consider only the first 16 bits how the results come alright. Can anybody kindly explain to me with a sample value.

2) Secondly how the values declared in the MAXPWRH & MAXPWRL registers are arrived at. ie., 0x98CE and 0xB3f1

I am unable to proceed further without understanding these register reading conversion. If anybody has worked on this application note or worked with CS5460A should be able to help me out.

Thankyou
