Overview
The ADR530BRT-R2 is a high precision shunt voltage reference manufactured by Analog Devices Inc. It provides a nominal output voltage of 3.0 V with an initial accuracy of ±0.2% and a maximum temperature coefficient of 40 ppm/°C. The device operates within an industrial temperature range of −40°C to +85°C and requires a minimum operating current of 50 μA, supporting up to 15 mA. It is housed in a 3-Lead SOT-23-3 package.
Feature Summary
- Ultracompact 3-Lead SOT-23-3 package design for space-critical applications
- Pin compatible with LM4040/LM4050 devices
- Eliminates the need for external compensation capacitors while remaining stable with any capacitive load
- Includes a trim terminal allowing output voltage adjustment over a ±0.5% range without affecting temperature coefficient
Applications
- Portable, battery-powered equipment
- Automotive systems
- Data acquisition systems
- Instrumentation and process control
- Energy measurement
Procurement Notes
Verify the specific ordering suffix R2 against official documentation to confirm the reel quantity and packaging configuration. Ensure the selected variant matches the required package type and compliance standards for your manufacturing process. Cross-reference the part number with the manufacturer's current ordering guide to validate availability and specifications before procurement.
Selection Notes
Select this component when a precise 3.0 V reference is needed in a small footprint. The B grade offers superior accuracy compared to the A grade. Consider the trim terminal if system-level calibration is required. Verify that the bias resistor selection accommodates the full operating current range from 50 μA to 15 mA under varying supply conditions.
Part Context
This part belongs to the ADR520/ADR525/ADR530/ADR540/ADR550 series of high precision shunt mode voltage references. These devices utilize band gap technology to achieve low temperature drift and ultralow output noise. The series is designed for applications requiring stability and accuracy in compact form factors.
Replacement Considerations
The datasheet explicitly states pin compatibility with the LM4040 and LM4050. Designers replacing these legacy parts should verify that the new biasing requirements align with the ADR530's operating current specifications.
