AD736BRZ

Overview

The AD736BRZ is a low-power, precision monolithic true RMS-to-DC converter manufactured by Analog Devices. It features laser trimming for high accuracy, with a maximum error of ±0.3mV ±0.3% reading on sine wave inputs. The device operates from a wide power supply range of +2.8V/-3.2V to ±16.5V and consumes a maximum supply current of 200µA. It provides a buffered voltage output with specified precision requiring no external trimming. The component is housed in an 8-pin SOIC-N package and supports operation temperatures from -40°C to +85°C.

Feature Summary

• Laser-trimmed architecture ensures high measurement accuracy across diverse input waveforms including pulses and phase-controlled sine waves.
• Integrated buffer amplifier delivers precise voltage output without the need for external calibration components.
• Low power consumption design enables extended battery life in portable instrumentation applications.

Applications

• Portable digital multimeters
• Battery-powered test equipment
• Precision rectifier circuits

Procurement Notes

Verify the specific suffix BRZ indicates the commercial temperature grade (-40°C to +85°C) and SOIC-8 packaging. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure supply chain sources provide valid traceability for this Analog Devices part number.

Selection Notes

Select the AD736BRZ when high precision RMS conversion is required for non-sinusoidal signals in space-constrained designs. Compare against industrial grade variants if extended temperature ranges beyond +85°C are necessary. Evaluate power budget constraints as the device draws 200µA maximum supply current.

Part Context

This component belongs to the AD736 family of RMS-to-DC converters designed for cost-effective precision signal processing. It replaces discrete solutions offering superior accuracy and reduced board space. The BRZ variant specifically denotes the commercial temperature range and lead-free compliant packaging standard.
