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 mVg0.05% typ) for decade ranges i.e., 10 mV100 mV, 0.7V7V, etc.
If Military/Aerospace specified devices are required, please contact the National Semiconductor Sales Office/Distributors for availability and specifications.
