The 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. 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.
