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
0 EOUT(DC) e
1
T
T
EIN2(t) dt

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
x xranges i e 10 mV 100 mV 0 7V 7V etc
