MX536A集成电路（IC）的RMS至DC转换器规格书PDF中文资料

General Description

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 7VRMSfor the MX536A and 0 to 200mVRMSfor 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.
