AD636KHZ

Overview

The AD636KHZ is a low power monolithic true RMS-to-DC converter designed for accurate measurement of complex input waveforms. It performs conversion on signals ranging from 0 mV to 200 mV rms, accommodating crest factors up to 6 with minimal additional error. The device features a 1 MHz bandwidth and provides a dB output with a 50 dB range. It operates on single or dual supplies with an 800 μA quiescent current. Packaged in a TO-100 metal can, it supports through-hole mounting within a 0°C to +70°C operating temperature range.

Feature Summary

• Performs true RMS-to-DC conversion on low-level AC and DC signals
• Laser-trimmed for high accuracy with maximum error specifications
• Supports wide response capability with 1 MHz bandwidth
• Enables accurate measurement of complex waveforms with high crest factor tolerance

Applications

• Measurement of complex input waveforms requiring true RMS calculation
• Low level signal processing in precision instrumentation
• Power monitoring applications involving AC and DC signal components

Procurement Notes

Verify the specific suffix KHZ corresponds to the TO-100 package and laser-trimmed accuracy grade. Confirm that the component meets the required environmental operating temperature range of 0°C to +70°C. Ensure the design accommodates the specified 200 mV full-scale input range and 800 μA quiescent current constraints. Cross-reference the manufacturer datasheet for pinout compatibility and thermal management requirements associated with the metal can package.

Selection Notes

Select this component when precise RMS conversion of low-level signals is required without the cost of hybrid converters. It is suitable for designs needing wide bandwidth and high crest factor tolerance. Consider the TO-100 package for through-hole assembly needs. Evaluate the single or dual supply options based on system power architecture. Ensure the input signal amplitude remains within the specified 0 mV to 200 mV rms range for optimal performance.
