There is little to say about the true r.m.s.
converter. The circuit diagram
shows a standard application of
the AD736JN, connected to a non-critical
R-C network, C4-RI5, and three
electrolytic capacitors (also uncrttical).
C5, C6 and C7, The bandwidth of the
true-r.m.s. converter exceeds that of
the multimeter IC input by far. In fact,
the multimeter Je limits the -1%-
bandwidth of the DMM to about
300 Hz. Keep this in mind when measuring
signals with a lot of dtstortion
[i.e. containing many higher harrnonics),
because for the measurement to
be accurate. the strongest harmorucs
have to fall within the 300- Hz bandwidth
of the DMM.
