AD8436BRQZ-R7

Overview

The AD8436BRQZ-R7 is a low-power true RMS-to-DC converter manufactured by Analog Devices Inc. It operates within an input voltage range of 4.8 V to 36 V and delivers a maximum output voltage of 5 V. The device features a working supply current of 300 uA and supports an output current of 15 mA. It is housed in a QSOP-20 package with surface mount installation. The component functions across a temperature range from -40 C to +125 C, with a power dissipation rating of 1.1 W.

Feature Summary

• Performs true root-mean-square to direct current conversion for accurate signal measurement.

Applications

• Power monitoring systems
• Signal processing circuits requiring RMS calculation

Procurement Notes

Verify availability status carefully as the component may be subject to limited supply or factory special orders. Confirm that the QSOP-20 package variant matches design requirements. Ensure operating conditions remain within the specified -40 C to +125 C range during implementation.

Selection Notes

Select this component when true RMS conversion is required with low quiescent current consumption. The wide input voltage range supports various power supply configurations. Verify thermal management capabilities given the 1.1 W power dissipation specification in the target application environment.

Part Context

This part belongs to the AD8436 series of specialized power management ICs designed for precision analog signal conditioning. It serves as a dedicated converter for transforming AC signals into proportional DC voltages representing their RMS values.

Replacement Considerations

Check for AD8436BRQZ as a tube-packaged alternative from the same manufacturer family if reel packaging constraints apply.
