ADR5041AKSZ-REEL

Overview

The ADR5041AKSZ-REEL is a precision micropower shunt mode voltage reference manufactured by Analog Devices. It provides a fixed output voltage of 2.5 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. Housed in an ultracompact SC-70 (KS) package, it requires no external compensation capacitor for stability.

Feature Summary

• Ultracompact SC-70 package design optimized for space-critical applications
• High precision performance with ±0.1% initial accuracy and low temperature drift
• Wide operating current range supporting both micro-power and higher load conditions
• Stable operation without the need for external compensation capacitors

Applications

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

Procurement Notes

Verify the specific ordering suffix REEL7 corresponds to the required reel quantity of 3,000 units. Confirm that the KS package option matches the PCB footprint requirements. Ensure the Grade B specification aligns with the necessary accuracy and temperature coefficient tolerances for the target application environment.

Selection Notes

Select this component when a stable 2.5 V reference is needed in a minimal footprint. The wide input current capability allows flexibility in bias resistor selection. Consider the thermal resistance characteristics of the SC-70 package for heat dissipation needs. Verify compatibility with existing supply voltages and load requirements.
