Datasheet
The MX536A and MX636 are true RMS-to-DC convert-
ers. They feature low power and are designed to accept
low-level input signals from 0 to 7V
and 0 to 200mV
complex input waveforms containing AC and DC com-
ponents. They can be operated from either a single sup-
ply or dual supplies. Both devices draw less than 1mA
of quiescent supply current, making them ideal for bat-
tery-powered applications.
Input and output offset, positive and negative waveform
symmetry (DC reversal), and full-scale accuracy are
laser trimmed, so that no external trims are required to
achieve full rated accuracy.
