True RMS-to-DC IC

True RMS-to-DC IC

MX536A and MX636Maxim-ICThe MX536A and MX636 are true RMS-to-DC converters.
They feature low power and are designed to accept
low-level input signals from 0 to 7VRMS for the MX536A
and 0 to 200mVRMS for the MX636. Both devices accept
complex input waveforms containing AC and DC components.
They can be operated from either a single supply
or dual supplies. Both devices draw less than 1mA
of quiescent supply current, making them ideal for battery-
powered applications.
