5962-8963701CA

Overview

The 5962-8963701CA is a high precision, wideband RMS-to-DC converter manufactured by Analog Devices Inc. It computes the true RMS value of complex waveforms with a maximum nonlinearity of 0.02% for inputs between 0 V and 2 V RMS. The device features a crest factor compensation scheme allowing measurements of signals with crest factors up to 10 with less than 1% additional error. It offers a bandwidth of 8 MHz at 2 V RMS input and 600 kHz at 100 mV RMS input. The component supports chip select-power down functionality, reducing quiescent current from 2.2 mA to 350 μA.

Feature Summary

• Computes true RMS values of complex waveforms with high accuracy
• Includes crest factor compensation for signals with crest factors up to 10
• Supports analog three-state operation via chip select-power down feature
• Provides multiple output formats including square, mean square, absolute value, and dB

Applications

• Precision signal measurement systems requiring true RMS computation
• Audio and RF signal analysis equipment
• Industrial process control instrumentation
• Test and measurement devices for waveform characterization

Procurement Notes

Verify the specific revision level (Rev K or Rev L) required for your design, as datasheet versions may differ. Confirm package availability in CERDIP format, as this is a specialized military-grade component. Check for obsolescence status or lifecycle changes directly with Analog Devices, as distribution channels may vary. Ensure compatibility with existing board layouts for the side-brazed DIP or CERDIP packages before finalizing procurement plans.

Selection Notes

Select this component when high accuracy and wide bandwidth are critical for RMS conversion tasks. It is suitable for applications involving complex waveforms where crest factor errors must be minimized. Consider the power-down feature if energy efficiency during idle periods is a requirement. Evaluate the need for external reference components and ensure the operating temperature range meets environmental specifications.
