AD8436ARQZ-R7

Overview

The AD8436ARQZ-R7 is a low-power true RMS-to-DC converter manufactured by Analog Devices Inc. It operates within a supply voltage range of 4.8 V to 36 V or ±2.4 V to 18 V, with a typical operating current of 325 µA. The device features a maximum output current capability of 15 mA and supports an output voltage range from -5 V to +5 V. Designed for surface-mount applications, it is housed in a 20-QSOP package. The component functions reliably across an extended industrial temperature range spanning from -40°C to +125°C.

Feature Summary

• Performs true root-mean-square to direct-current conversion
• Supports wide single-supply and dual-supply voltage operation
• Delivers rail-to-rail output swing capability

Applications

• Power monitoring systems
• Audio signal processing
• Thermal measurement instrumentation

Procurement Notes

Verify the specific ordering suffix against the manufacturer datasheet to ensure correct packaging configuration. Confirm that the 20-QSOP package variant matches the intended board layout requirements. Check RoHS compliance status and moisture sensitivity level classifications prior to assembly planning. Ensure the selected revision aligns with current production availability and lead time constraints.

Selection Notes

Select this component when accurate RMS measurement of AC signals is required over a wide dynamic range. Consider the low quiescent current for battery-operated or energy-efficient designs. Evaluate the thermal performance within the specified -40°C to +125°C operating window. Verify that the input voltage limits accommodate the system's maximum transient conditions without exceeding the absolute maximum ratings.

Part Context
