AD536ASH

Overview

The AD536ASH is a monolithic true RMS-to-DC converter manufactured by Analog Devices Inc. It operates within an extended industrial temperature range of -55°C to +125°C and utilizes a 10-pin TO-100 metal can package for through-hole mounting. The device features a maximum input voltage of 7 V and a supply current of 1.2 mA. It provides a logarithmic dB output with a 60 dB dynamic range, enabling direct conversion of RMS signal levels.

Feature Summary

• Performs direct calculation of the RMS value for composite AC and DC signals without requiring external adjustment due to factory laser trimming.
• Includes a peak factor compensation table that maintains measurement accuracy within 1% error for waveforms with peak factors up to 7.
• Converts RMS signal levels into a logarithmic dB output on a dedicated pin, facilitating wide dynamic range analysis.

Applications

• Measurement of complex signals in audio and vibration analysis systems
• Power monitoring applications requiring accurate RMS power calculations
• Instrumentation utilizing battery-powered or low-power supply constraints

Procurement Notes

Verify the specific suffix 'ASH' to confirm the military-grade temperature rating (-55°C to +125°C) and TO-100 package style. Ensure compatibility with existing circuit layouts designed for the standard AD536A family. Confirm availability status as distribution may be limited for this specific variant.

Selection Notes

Select the AD536ASH when operation in extreme temperatures exceeding commercial limits is required. This variant offers higher precision compared to basic models while maintaining low static current consumption suitable for sensitive measurement environments.

Part Context

This component belongs to the AD536A series of RMS-to-DC converters. It serves as an enhanced replacement for the legacy AD536, offering improved bandwidth and tighter temperature drift specifications. The device integrates rectification, squaring, averaging, and square-rooting functions onto a single silicon chip.

Replacement Considerations

The AD536AJHZ is a verified substitute part number within the same product family.
