AD636JDZ

Overview

The AD636JDZ is a monolithic true RMS-to-DC converter manufactured by Analog Devices Inc. It utilizes a proprietary squaring, averaging, and square-rooting architecture to compute the root-mean-square value of an input signal with high accuracy. The device operates within a temperature range of 0°C to +70°C and is housed in a 14-pin SBCDIP package. It supports a minimum output current of 5 mA and functions with supply voltages ranging from -18 V to -3 V for the negative rail.

Feature Summary

• Monolithic implementation of true RMS-to-DC conversion circuitry
• High linearity performance with minimal linear error
• Integrated analog computation for signal processing

Applications

• Precision power measurement systems
• Audio level metering and analysis
• Vibration monitoring instrumentation

Procurement Notes

Verify the specific suffix JDZ corresponds to the commercial temperature grade and leaded DIP packaging configuration. Confirm RoHS compliance status and lead content requirements against project specifications. Ensure the supplier provides valid traceability documentation for the Analog Devices Inc. manufacturing origin.

Selection Notes

Select this component when accurate RMS calculation of complex waveforms is required without external computational blocks. Consider the 14-pin through-hole form factor for prototyping or legacy board designs. Evaluate the 5 mA output drive capability against downstream load requirements before finalizing the design.

Part Context

This part belongs to the AD636 family of precision analog signal processors designed for direct RMS computation. It serves as a dedicated solution for applications requiring high dynamic range and wide bandwidth performance in analog domains.

Replacement Considerations

Cross-reference with other ADI RMS converters such as the AD637 series for extended temperature ranges or different pinout configurations.
