Overview
The ADR550BKS-R2 is a high precision shunt voltage reference manufactured by Analog Devices Inc. It provides a nominal output voltage of 5.0 V with an initial accuracy of ±0.2%. The device features a maximum temperature coefficient of 40 ppm/°C and operates within an industrial temperature range of −40°C to +85°C. It requires no external compensation capacitor, maintains stability with any capacitive load, and supports an operating current range from 50 μA to 15 mA.
Feature Summary
- Ultracompact SC70 package design suitable for space-critical applications
- Pin compatible with industry-standard LM4040/LM4050 references
- Integrated trim terminal allows adjustment of the output voltage over a ±0.5% range without affecting the temperature coefficient
Applications
- Portable, battery-powered equipment
- Automotive systems
- Data acquisition systems
- Instrumentation and process control
- Energy measurement
Procurement Notes
Verify that the specific ordering suffix matches the required packaging format, as the datasheet lists both reel and cut tape options for this part number. Confirm compliance with RoHS standards if applicable to your manufacturing requirements. Ensure the selected component meets the specified industrial temperature range and electrical characteristics for your circuit design.
Selection Notes
Select this component when a precise 5.0 V reference is needed in a compact footprint. The B-grade designation ensures tighter initial accuracy and lower temperature drift compared to the A-grade variant. Consider the trim terminal capability if system-level calibration is required to compensate for board-level errors or resistor tolerances.
Part Context
This device belongs to the ADR520/ADR525/ADR530/ADR540/ADR550 series of high precision shunt voltage references. The series utilizes band gap technology to achieve low temperature drift and ultralow noise performance. These references are designed to operate without external capacitors while remaining stable with any capacitive load, making them versatile for various power supply and data acquisition applications.
Replacement Considerations
The datasheet confirms pin compatibility with the LM4040 and LM4050. Designers replacing these legacy components should verify that the replacement meets the specific accuracy and temperature coefficient requirements of the original design.
