AD737JR-REEL7

Overview

The AD737JR-REEL7 is a low-cost, low-power true RMS-to-DC converter manufactured by Analog Devices Inc. It computes the true root-mean-square value of an input signal and provides a DC output proportional to that value. The device features a full-scale input range of 200 mV and offers high accuracy with a maximum input bias current of 25 pA. It operates within a supply voltage range of 2.8 V to 16.5 V and supports a minimum operating temperature of -40°C and a maximum of +85°C. The component is housed in an SOIC-8 package.

Feature Summary

• Computes true RMS values directly from AC signals
• Provides direct interfacing capability with 3 1/2 digit CMOS A/D converters
• Features high input impedance and low input bias current for minimal signal loading

Applications

• Signal processing systems requiring accurate power measurement
• Audio level metering and analysis
• Industrial process control instrumentation

Procurement Notes

Verify the specific suffix JR-REEL7 against the official Analog Devices datasheet to confirm the reel packaging configuration and tape specifications. Ensure the procurement source provides valid traceability documentation for this specific part number variant. Confirm RoHS compliance status through the manufacturer's official certification records prior to ordering.

Selection Notes

Select this component when true RMS conversion is required for signals with complex waveforms where average-responding meters would yield inaccurate results. Consider the 200 mV full-scale input range and the need for external attenuation if input levels exceed this limit. Evaluate the low power consumption requirements against the available supply voltage range of 2.8 V to 16.5 V.

Part Context

The AD737 series represents a family of precision RMS-to-DC converters designed for cost-sensitive applications. The AD737JR-REEL7 specifically denotes the reel-packaged version of the AD737JR variant. This series is engineered to provide high accuracy and stability, making it suitable for general-purpose analog signal conditioning tasks in industrial and consumer electronics.

Replacement Considerations

Consult the official Analog Devices replacement guide for verified cross-reference part numbers. Ensure any substitute maintains the true RMS functionality and compatible pinout configuration.
