AD737JRZ-5-R7

Overview

The AD737JRZ-5-R7 is a precision RMS-to-DC converter IC manufactured by Analog Devices Inc. It operates within a supply voltage range of 2.5 V to 16.5 V and draws a typical operating current of 160 uA. The device is housed in an 8-pin SOIC package with surface-mount installation. It functions across an extended temperature range from -40°C to +85°C, supporting single-supply applications requiring accurate AC signal measurement.

Feature Summary

• Performs true root-mean-square to direct-current conversion for accurate AC signal measurement
• Operates efficiently with low quiescent current consumption suitable for power-sensitive designs
• Features wide single-supply voltage compatibility for flexible power integration

Applications

• AC voltage and current measurement systems
• Power monitoring circuits
• Audio level detection and metering
• Industrial process control instrumentation

Procurement Notes

Verify the specific suffix configuration against official Analog Devices documentation to ensure correct output scaling and pinout alignment. Confirm RoHS compliance status through manufacturer declarations prior to procurement. Validate that the reel packaging matches production line requirements. Cross-reference the full part number with authorized distributor catalogs to confirm availability and authenticity.

Selection Notes

Select this component when precise RMS conversion is required within a limited power budget. The wide input voltage range accommodates various supply rails without additional regulation. Ensure the thermal environment remains within the specified operational limits. Consider the SOIC package dimensions for PCB layout constraints compared to through-hole alternatives.

Part Context

This device belongs to the AD737 series of specialized power management integrated circuits designed for analog signal processing. It serves as a dedicated solution for converting varying AC amplitudes into proportional DC voltages. The family emphasizes accuracy and stability for measurement applications where traditional averaging rectifiers fail to provide true effective value readings.
