ADR4540DEZ-R7

Overview

The ADR4540DEZ-R7 is a high-precision, low-noise series voltage reference from Analog Devices. It provides a fixed output of 4.096 V with an initial accuracy of ±0.02%. The D-grade specification ensures a maximum temperature coefficient of 0.8 ppm/°C over the 0°C to +70°C range. Operating within a supply voltage of 3 V to 15 V, it draws a maximum quiescent current of 950 μA and supports ±10 mA load currents. The device is housed in an 8-lead LCC package.

Feature Summary

Ultra-low noise performance for signal integrity
High initial accuracy with minimal drift
Excellent thermal stability across operating ranges
Low dropout voltage for portable applications

Applications

Precision data acquisition systems
High resolution data converters
Industrial instrumentation
Medical devices
Automotive battery monitoring

Procurement Notes

Verify the specific grade suffix (D) and package type (LCC) against project requirements. Confirm that the restricted temperature range (0°C to +70°C) aligns with environmental conditions. Ensure input voltage remains within the specified 3 V to 15 V limits during operation.

Selection Notes

Select this component when ultra-low noise and high precision are critical. The D-grade offers superior temperature stability compared to B or A grades but operates within a narrower temperature window. Consider the LCC package for space-constrained designs requiring Kelvin sensing capabilities.

Part Context

This part belongs to the ADR4540 family of ultralow noise voltage references. It shares core topology features with other members like the ADR4520 and ADR4550 but is distinguished by its specific 4.096 V output and D-grade thermal specifications. The family utilizes innovative design techniques to minimize hysteresis and long-term drift.
