AD636JD

Overview

The AD636JD is a low-power monolithic integrated circuit designed for true root-mean-square to direct current conversion. It processes low-level signals within a specified range of 0 mV to 200 mV rms. The device accommodates signal crest factors up to 6 with minimal additional error, ensuring accurate measurement of complex waveforms. It features a wide response capability with a 1 MHz negative three decibel bandwidth for signals exceeding 100 mV rms. The component operates on single or dual power supplies and maintains a quiescent current of 800 microamperes.

Procurement Notes

Verify the specific suffix designation against official Analog Devices documentation to confirm accuracy class and package type. Ensure the ordering part number matches the required performance specifications and physical form factor. Cross-reference the manufacturer's latest datasheet revision to confirm pinout compatibility and electrical characteristics before finalizing procurement orders.

Selection Notes

Select this component when precise RMS conversion of low-level signals is required without the complexity of hybrid converters. Consider the maximum error specification relative to the application's tolerance requirements. Evaluate the operating temperature range and supply voltage constraints to ensure compatibility with the system design. The low power consumption makes it suitable for battery-operated or thermally sensitive environments.
