Overview
The ADR540BKS-REEL7 is a high precision shunt voltage reference from Analog Devices, housed in an ultracompact SC70 package. It provides a nominal output voltage of 4.096 V with Grade B 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. Designed for space-critical applications, it requires no external compensation capacitor while remaining stable with any capacitive load.
Feature Summary
- Ultracompact SC70 package design suitable for space-constrained layouts
- Pin compatible with LM4040/LM4050 standards for direct replacement
- Eliminates the need for external compensation capacitors
- Trim terminal allows adjustment of output voltage over a ±0.5% range
Applications
- Portable, battery-powered equipment
- Automotive systems
- Data acquisition systems
- Instrumentation and process control
- Energy measurement
Procurement Notes
Verify the specific ordering suffix against official documentation to confirm package type and RoHS compliance status. Confirm that the 'B' grade designation matches the required initial accuracy specifications for the target application. Ensure the SC70 footprint aligns with the PCB layout constraints before finalizing procurement orders.
Selection Notes
Select this component when a precise 4.096 V reference is required in minimal physical space. The Grade B variant offers tighter initial accuracy compared to Grade A options. Consider the operating current range requirements, as the device functions between 50 μA and 15 mA. Verify thermal management needs given the small surface mount package dimensions.
Part Context
This part belongs to the ADR520/ADR525/ADR530/ADR540/ADR550 series of high precision shunt voltage references. The series utilizes band gap concepts to achieve low temperature drift. The ADR540 specifically targets applications requiring a 4.096 V output level, complementing other voltages like 2.048 V, 2.5 V, 3.0 V, and 5.0 V available in the family.
Replacement Considerations
The datasheet explicitly states pin compatibility with the LM4040 and LM4050. Designers can consider these parts for direct replacements if system constraints allow.
