AD736KR-REEL7

Overview

The AD736KR-REEL7 is a low-power, precision monolithic true RMS-to-DC converter manufactured by Analog Devices Inc. It features laser trimming for high accuracy with a maximum error of ±0.3mV ±0.3% reading on sine wave inputs. The device maintains precision across diverse input waveforms, including variable duty cycle pulses and phase-controlled sine waves. It operates from a wide supply voltage range of +2.8V/-3.2V to ±16.5V with a maximum supply current of 200µA. The component includes an internal output buffer amplifier and supports AC coupling via an external capacitor. It is housed in an 8-pin SOIC package.

Feature Summary

• Laser-trimmed precision architecture ensuring minimal measurement error across varied signal types
• Integrated output buffer amplifier providing design flexibility without external calibration
• Low power consumption optimized for battery-operated portable instrumentation
• Capability to process complex waveforms including pulsed and phase-controlled signals

Applications

• Portable digital multimeters
• Battery-powered test equipment
• Precision rectifier circuits requiring RMS conversion
• Signal processing in industrial monitoring systems

Procurement Notes

Verify the specific suffix REEL7 indicates tape and reel packaging when ordering. Confirm the K grade temperature rating aligns with your operational environment requirements. Ensure compatibility with the 8-pin SOIC footprint during PCB layout. Cross-reference the latest datasheet for any updates regarding lead-free compliance or material declarations before finalizing procurement specifications.

Selection Notes

Select this component when high accuracy is required for non-sinusoidal waveforms compared to standard average-responding meters. Consider the low supply current if power efficiency is critical for portable designs. Evaluate the wide supply voltage range against your system's power rails. Verify that the 8-pin SOIC package fits within your available board space constraints.

Part Context

This part belongs to the AD736 family of true RMS-to-DC converters. It shares core functionality with variants like the AD736JRZ but differs in packaging and potentially temperature grade. The REEL7 suffix specifically denotes reel packaging for automated assembly processes. It serves as a direct replacement for older analog solutions offering superior accuracy and lower power consumption.

Replacement Considerations

The AD736JRZ-R7 is a documented alternative within the same product family. Verify pinout compatibility and temperature range specifications before substitution. Ensure the replacement variant meets the specific packaging requirements of your manufacturing line.
