AD536ASD/883B AD536A Series RMS-to-DC Converter
5V to 36V Supply Range x 0.5% Total Error — Military-Grade True RMS-to-DC Conversion
AD536ASD/883B Product Overview
The AD536ASD/883B is a complete monolithic true RMS-to-DC converter from the AD536A Series, designed for the electronic measurement of complex AC and DC input waveforms with high accuracy and wide bandwidth. The 14-pin CERDIP military-grade variant features laser-trimmed accuracy and a unique auxiliary dB output pin with a 60 dB dynamic range.
Rated for a supply range of 5 V to 36 V (or ±3 V to ±18 V) with a 450 kHz bandwidth for signals above 100 mV, it outputs a DC voltage equivalent to the true RMS value of the input with 0.5% total maximum error (AD536AS grade). The -3 dB bandwidth is 450 kHz (2 MHz for signals >1 V) and supply current is 1.2 mA quiescent. Mass is approximately 2.714 g and operating temperature range is -55°C to +125°C (military grade). The input circuitry features full overload protection well beyond supply levels, and the output is short-circuit protected.

AD536ASD/883B Key Advantages
The AD536ASD/883B employs monolithic true RMS-to-DC conversion with crest factor compensation, delivering 0.5% total accuracy while directly computing the true RMS value of any complex waveform containing AC and DC components. The 450 kHz bandwidth provides high-frequency signal measurement capability, while the unique auxiliary dB output with 60 dB range captures logarithmic signal levels for direct decibel conversion. The 14-pin CERDIP hermetically sealed package accommodates harsh military and aerospace environments and the through-hole mounting enables reliable, ruggedized assembly. The 883B screening level ensures compliance with stringent military reliability requirements.
