AD637 Datasheet (Analog Devices) - Wide-Band RMS-to-DC Converter

AD637, Wide-Band RMS-to-DC Converter

The AD637 is a complete, high accuracy, rms-to-dc converter that computes the true rms value of any complex waveform.

It offers performance that is unprecedented in integrated circuit rms-to-dc converters and comparable to discrete and modular techniques in accuracy, bandwidth, and dynamic range.

AD637 Features
