ADR370BRTZ-REEL7

Overview

The ADR370BRTZ-REEL7 is a precision, low-power, 2.048 V series band gap voltage reference manufactured by Analog Devices Inc. It operates within an input voltage range of 2.3 V to 15 V and delivers high accuracy with an initial error of ±4 mV (±0.2%). The device features a maximum temperature coefficient of 50 ppm/°C across the extended industrial range of −40°C to +125°C. It consumes a maximum quiescent current of 72 μA while providing a minimum output sink/source current of ±5 mA. Packaged in a compact 3-lead SOT-23 format, it includes line regulation of 20 ppm/V and load regulation of 400 μV/mA.

Feature Summary

Patented temperature drift curvature correction design techniques ensure high stability and precise matching of internal components.
Micropowered architecture allows operation with minimal supply headroom while sourcing or sinking up to 5 mA of load current.
Compact 3-lead SOT-23 package provides a small footprint suitable for space-constrained portable applications.

Applications

Battery-powered instrumentation
Portable medical instruments
Data acquisition systems
Industrial process control systems
Automotive

Procurement Notes

Verify that the specific ordering suffix matches the required RoHS compliance status, as indicated by the 'Z' designation in the part number. Confirm the grade selection corresponds to the necessary initial accuracy specifications. Ensure the procurement channel sources genuine Analog Devices components to maintain specified electrical performance and reliability standards.

Selection Notes

Select this component when a stable 2.048 V reference is required in systems operating between 2.3 V and 15 V. It is suitable for designs prioritizing low power consumption alongside high accuracy. Consider the B-grade specifications for tighter tolerance requirements compared to the A-grade alternative. Evaluate thermal management needs based on the specified junction-to-ambient resistance values.

Part Context

This device belongs to the ADR370 family of micropowered voltage references. It utilizes a band gap concept to generate a stable output voltage by summing a positive temperature coefficient voltage with the negative temperature coefficient of a forward-biased silicon transistor base-emitter voltage. The family offers different grades to accommodate varying accuracy and cost constraints.
