AD536AJHZ

Overview

The AD536AJHZ is a monolithic true RMS-to-DC converter manufactured by Analog Devices Inc. It operates within a supply voltage range of 5V to 36V and draws a typical quiescent current of 1.2 mA. The device provides an output current capability of 5 mA and features a bandwidth of 450 kHz for signals above 100 mVrms, extending to 2 MHz for signals above 1Vrms. It has a maximum reading error of ±5 mV plus 0.5% and supports a crest factor up to 7 with only 1% error. The component is housed in a TO-100-10 metal can package with ten pins, designed for through-hole mounting.

Feature Summary

• Performs direct calculation of the RMS value of input waveforms, including AC and DC components, without requiring external computation circuits.
• Includes an internal crest factor compensation table that maintains measurement accuracy for complex signals with high peak-to-RMS ratios.
• Features a dedicated logarithmic output pin capable of converting the RMS signal level into a dB representation over a 60 dB dynamic range.
• Incorporates laser-trimmed circuitry at the wafer level to ensure precision and eliminate the need for external adjustment.

Applications

• Audio power measurement systems
• Vibration analysis instrumentation
• Battery-powered test equipment

Procurement Notes

Verify the specific suffix 'HZ' against the manufacturer's official documentation to confirm the exact package variant and compliance status. Ensure the procurement channel sources from authorized distributors to guarantee authenticity. Confirm that the required operating temperature range aligns with the commercial grade specifications provided in the datasheet.

Selection Notes

Select this component when accurate RMS conversion of mixed AC/DC signals is required with minimal external parts. Consider the 450 kHz bandwidth limit for higher frequency applications. Evaluate the TO-100-10 package constraints for PCB layout. Compare against the AD536ASH if extended industrial temperature ranges are necessary.

Part Context

This part belongs to the AD536A family of RMS-to-DC converters, which succeeded the original AD536 design. The family offers improved bandwidth and temperature drift characteristics compared to its predecessor. The AD536AJHZ represents the commercial grade version with specific accuracy tolerances defined for standard operating environments.

Replacement Considerations

The AD536ASH is a verified substitute offering the same functionality but with an extended temperature range of -55°C to 125°C. Verify pin compatibility and thermal requirements before substitution.
