AD536AJDZ

Overview

The AD536AJDZ is a monolithic RMS-to-DC converter IC manufactured by Analog Devices Inc. It operates within a supply voltage range of 5V to 36V and features a maximum quiescent current of 1.2 mA. The device provides an output current capability of 5 mA and dissipates up to 500 mW. It utilizes a 14-pin CDIP package with through-hole mounting. The component supports a bandwidth of 450 kHz for signals above 100 mVrms and 2 MHz for signals above 1 Vrms. It offers a peak factor compensation table allowing measurements up to a crest factor of 7 with 1% error, and includes a logarithmic dB output spanning 60 dB.

Feature Summary

• Performs direct RMS calculation of AC and DC input signals without external adjustment
• Includes integrated peak factor compensation table for complex signal measurement
• Provides logarithmic dB output conversion over a 60 dB dynamic range
• Features laser-trimmed internal calibration for high accuracy

Applications

• Power monitoring systems requiring true RMS measurement
• Audio level metering and analysis
• Vibration measurement instrumentation
• Battery-powered test equipment due to low static current

Procurement Notes

Verify the specific suffix 'JDZ' indicates the commercial grade (A) variant in the 14-pin ceramic DIP package. Confirm the manufacturer is Analog Devices Inc. Ensure the part matches the specified pinout and physical dimensions for the CDIP-14 footprint. Check for RoHS compliance status as indicated in official documentation.

Selection Notes

Select this component when precise RMS conversion of mixed AC/DC signals is required. It is suitable for applications needing wide bandwidth and peak factor compensation. Consider the 14-pin CDIP package for through-hole assembly requirements. Evaluate the 0.5% maximum reading error specification against system accuracy needs.

Part Context

The AD536AJDZ belongs to the AD536A family of RMS-to-DC converters. It serves as an improved replacement for the legacy AD536, offering enhanced bandwidth and temperature drift characteristics. The device integrates absolute value circuits, squarers/dividers, and current mirrors into a single chip, eliminating the need for discrete component combinations.
