AD8436JCPZ-WP

Overview

The AD8436JCPZ-WP is a low-cost, 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 typical operating supply current of 325 uA and an input current of 300 uA, with an output current capability of 15 mA. It is housed in an LFCSP-20 package and functions reliably across a temperature range of 0°C to +70°C.

Feature Summary

• Performs true root-mean-square to direct-current conversion for accurate signal measurement
• Operates on a single power supply with a wide input voltage range up to 36 V
• Designed for low-power applications with minimal quiescent current consumption

Applications

• Power monitoring systems requiring precise RMS measurements
• Industrial process control instrumentation
• Audio and RF signal level detection circuits

Procurement Notes

Verify the specific suffix WP indicates waffle pack packaging when sourcing. Confirm availability status as restricted supply may apply. Ensure the LFCSP-20 package matches your PCB footprint requirements. Check humidity sensitivity levels for proper storage and reflow soldering profiles during assembly.

Selection Notes

Select this component when true RMS accuracy is required over simple average-responding converters. Consider the 4.8 V minimum supply voltage constraint against your system rails. Evaluate the 15 mA output drive capability against load requirements. Verify thermal performance within the specified 0°C to +70°C operating range for your enclosure design.

Part Context
