AD637KQ

Overview

The AD637KQ is a true RMS-to-DC converter manufactured by Analog Devices Inc. It operates within a commercial temperature range of 0°C to +70°C and utilizes a 14-pin Ceramic Dual In-Line Package (CDIP). The device accepts input voltages ranging from 0 V to 7 V and provides an output voltage range of 2.2 V to 13.5 V. It supports a maximum output current of 6 mA.

Feature Summary

• Performs true root-mean-square to direct-current conversion
• Utilizes ceramic dual in-line package for through-hole mounting

Applications

• Signal processing circuits requiring RMS measurement
• Power monitoring systems
• Audio level detection

Procurement Notes

Verify the specific suffix KQ against official Analog Devices documentation to confirm the exact temperature grade and package variant. Ensure the CDIP footprint matches the target PCB design. Confirm RoHS compliance status with the manufacturer prior to procurement.

Selection Notes

Select this component when a commercial temperature range of 0°C to +70°C is sufficient for the application environment. The 14-pin CDIP package is suitable for through-hole assembly processes. Consider the 6 mA output current capability when designing load requirements.

Part Context

The AD637 series consists of precision true RMS-to-DC converters designed for accurate signal measurement. The KQ suffix denotes a specific commercial grade variant within the family, distinguished by its operating temperature range and ceramic packaging compared to other industrial or military grades.

Replacement Considerations

Cross-reference with AD637JDZ for equivalent functionality in a different package type. Verify pin compatibility and electrical specifications before substituting.
