ADR5040AKSZ-REEL

Overview

The ADR5040AKSZ-REEL7 is a precision micropower shunt mode voltage reference manufactured by Analog Devices Inc. It provides a nominal 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 reliably across an extended temperature range of −40°C to +125°C. Housed in an ultracompact SC-70 (KS-3) surface-mount package, it requires no external compensation capacitor for stability.

Feature Summary

• Ultracompact SC-70 package designed for space-critical applications
• High initial accuracy of ±0.1% with low temperature drift
• Wide operating current range suitable for battery-powered equipment
• Stable without external capacitors while supporting any capacitive load

Applications

• Portable, battery-powered equipment
• Automotive systems
• Data acquisition systems
• Instrumentation and process control
• Energy management

Procurement Notes

Verify the specific ordering suffix REEL7 corresponds to the required reel packaging configuration. Confirm that the KS package designation matches the intended SC-70 footprint requirements for the PCB layout. Ensure the Grade B specifications align with the design accuracy needs before finalizing procurement orders.

Selection Notes

Select this component when high precision is required in minimal board space. The ±0.1% accuracy grade offers tighter tolerance than standard options. Verify that the 2.048 V output level meets system reference requirements. Consider the 75 ppm/°C temperature coefficient for environments with significant thermal variations.

Part Context

This part belongs to the ADR504x family of precision shunt voltage references, which includes variants with different output voltages and accuracy grades. The AKSZ suffix indicates the 2.048 V output, Grade B accuracy, SC-70 package, and reel packaging format. It shares pin compatibility with industry-standard alternatives like the LM4040 series.

Replacement Considerations

Pin-compatible substitutes include the LM4040 and LM4050 series. For automotive applications, consider the ADR5040WARTZ-R7 variant which holds specific automotive qualifications.
