ADR5040AKSZ-REEL7

Overview

The ADR5040AKSZ-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 SC-70 (KS-3) surface-mount package.

Feature Summary

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

Applications

• Portable, battery-powered equipment
• Automotives
• Data acquisition systems
• Instrumentation and process control

Procurement Notes

Verify the specific ordering suffix KSZ indicates the SC-70 package configuration and REEL7 denotes the reel quantity. Confirm RoHS compliance status through official documentation. Ensure the selected grade meets the required initial accuracy and temperature coefficient specifications for the target application environment.

Selection Notes

Select this component when a precise 2.048 V reference is needed in a minimal footprint. The ±0.1% accuracy grade offers tighter tolerance than the standard ±0.2% variant. Consider the SC-70 package dimensions against available board space. Verify that the minimum operating current of 50 µA aligns with the system's quiescent power requirements.

Part Context

This part belongs to the ADR504x family of high-precision shunt voltage references. The family includes variants with different output voltages such as 2.5 V, 3.0 V, 4.096 V, and 5.0 V. The AKSZ suffix specifically identifies the 2.048 V output version packaged in the SC-70 form factor, distinguishing it from SOT-23 or automotive-grade alternatives.

Replacement Considerations

The datasheet notes pin compatibility with LM4040 and LM4050 devices. Designers should verify electrical parameters and package dimensions before substitution.
