LH0091 True RMS to DC Converter
General Description
The LH0091, rms to dc converter generates a dc output
equal to the rms value of any input per the transfer function:

The device provides rms conversion to an accuracy of 0.1%
of reading using the external trim procedure. It is possible to
trim for maximum accuracy (0.5 mV
