Overview
The ADR5040BRTZ-REEL7 is a precision micropower shunt mode voltage reference manufactured by Analog Devices Inc. It provides a fixed output voltage of 2.048 V with an initial accuracy of ±0.1% and a maximum temperature coefficient of 75 ppm/°C. The device operates within a wide current range from 50 µA to 15 mA and functions across an extended temperature range of −40°C to +125°C. It is housed in an ultracompact SOT-23-3 surface-mount package.
Feature Summary
- Designed for space-critical applications using ultracompact SC70 and SOT-23 packages
- Eliminates the need for external compensation capacitors while remaining stable with any capacitive load
- Features low temperature drift and fast settling time for high-precision data acquisition systems
Applications
- Portable, battery-powered equipment
- Automotive electronics
- Data acquisition systems
- Instrumentation and process control
- Energy management systems
Procurement Notes
Verify the specific grade B suffix and REEL7 packaging designation against the official Analog Devices ordering guide to ensure correct initial accuracy and temperature coefficient specifications. Confirm RoHS compliance status and automotive qualification requirements if applicable to the target design environment before finalizing procurement.
Selection Notes
Select this component when a precise 2.048 V reference is required in a minimal footprint. Ensure the bias resistor calculation accommodates the minimum operating current of 50 µA at the lowest supply voltage and the maximum current limit of 15 mA at the highest supply voltage to maintain stability and prevent thermal overload.
Part Context
This part belongs to the ADR504x family of high-precision shunt voltage references, which includes variants with outputs of 2.5 V, 3.0 V, 4.096 V, and 5.0 V. The family utilizes band gap concepts to achieve low temperature coefficients and is characterized over the industrial extended temperature range. It serves as a cost-effective alternative to larger discrete reference solutions.
Replacement Considerations
The datasheet explicitly states pin compatibility with LM4040 and LM4050 devices. Designers should verify that the electrical characteristics of these alternatives meet the specific accuracy and temperature coefficient requirements of the application.
