ADR434BRZ

Overview

The ADR434BRZ is a precision series voltage reference from the XFET family, manufactured by Analog Devices Inc. It provides a fixed output voltage of 4.096 V with an initial accuracy of ±1.5 mV (±0.04%) and a maximum temperature coefficient of 3 ppm/°C. The device operates within a supply voltage range of 6.1 V to 18 V, requiring a minimum headroom of 2 V. It features a quiescent current of 800 µA, sourcing up to 30 mA and sinking up to -20 mA. Noise performance is specified at 6.25 µV p-p (0.1 Hz to 10 Hz). It is housed in an 8-lead SOIC package and functions over an extended industrial temperature range of -40°C to +125°C.

Feature Summary

Utilizes XFET technology for low noise and low temperature drift performance
Capable of sourcing 30 mA and sinking 20 mA output current
Includes a trim terminal for adjusting output voltage without compromising performance

Applications

Precision data acquisition systems
High resolution data converters
Medical instruments
Industrial process control systems

Procurement Notes

Verify the specific suffix 'BRZ' corresponds to the B-grade specification and SOIC-8 packaging configuration. Confirm that the required input voltage meets the minimum 6.1 V threshold for proper regulation. Ensure thermal management aligns with the specified junction temperature limits during operation.

Selection Notes

Select this component when a stable 4.096 V reference is required with high accuracy and low drift. The B-grade rating ensures a tighter temperature coefficient compared to the A-grade variant. Consider the 2 V headroom requirement relative to the available supply voltage and load conditions.

Part Context

This part belongs to the ADR430/ADR431/ADR433/ADR434/ADR435 series of ultralow noise XFET voltage references. These devices share common architectural features including low supply current and high output drive capability, differentiated primarily by their fixed output voltage levels and specific grade accuracies.
