AD637JDZ

Overview

The AD637JDZ is a true RMS-to-DC converter integrated circuit manufactured by Analog Devices Inc. It operates within a supply voltage range of ±3V to ±18V and features a maximum linear error of 0.05%. The device supports a minimum output current of 6mA and functions across an operating temperature range of 0°C to +70°C. It utilizes a 14-pin SBCDIP package with dimensions of 19.94mm in length, 7.87mm in width, and 5.08mm in height.

Feature Summary

• Performs true root-mean-square to direct-current conversion
• Provides high precision with minimal linear error
• Supports wide dynamic input signal ranges

Applications

• Audio level measurement systems
• Power monitoring circuits
• Signal processing instrumentation

Procurement Notes

Verify the specific suffix JDZ corresponds to the 14-pin SBCDIP package variant when sourcing. Confirm RoHS compliance status and lead times directly with authorized distributors or Analog Devices representatives prior to ordering. Ensure the procurement channel provides valid traceability documentation for quality assurance purposes.

Selection Notes

Select this component when precise RMS calculation is required for complex waveforms beyond simple sine waves. Consider the 14-pin through-hole package constraint against available board space. Evaluate the ±3V to ±18V supply requirement against system power rails. Assess the 0°C to +70°C operating range against environmental conditions.

Part Context

This part belongs to the AD637 family of analog signal processors designed for accurate RMS conversion. It serves as a specialized PMIC function within broader mixed-signal applications. The JDZ suffix specifically denotes the ceramic dual in-line package configuration suitable for prototyping or industrial environments requiring robust mechanical mounting.
