ADR5044AKSZ-REEL

Overview

The ADR5044AKSZ-REEL7 is a precision micropower shunt voltage reference manufactured by Analog Devices Inc. It provides a fixed output voltage of 4.096 V with an initial accuracy of ±0.2% and a maximum temperature coefficient of 100 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-70-3 surface-mount package, it requires no external compensation capacitor for stability.

Feature Summary

• Ultracompact SC-70 package design suitable for space-critical applications
• Pin-compatible with LM4040/LM4050 for direct replacement
• Stable with any capacitive load without requiring external compensation

Applications

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

Procurement Notes

Verify the specific grade suffix (A vs B) and package option (KS vs RT) against project requirements, as these determine accuracy and temperature coefficient specifications. Confirm RoHS compliance status via the manufacturer's documentation. Ensure the ordering quantity matches the reel specification provided in the official datasheet ordering guide.

Selection Notes

Select this component when a stable 4.096 V reference is needed in a small footprint. The Grade A variant offers ±0.2% accuracy and 100 ppm/°C drift. Consider stacking multiple units if higher voltages are required, noting that errors accumulate. Ensure the bias resistor allows operation between the minimum 50 µA and maximum 15 mA limits under all supply conditions.

Part Context

This part belongs to the ADR504x family of precision shunt references, which includes variants with outputs of 2.048 V, 2.5 V, 3.0 V, 4.096 V, and 5.0 V. The family shares common features such as low power consumption and high precision. The 'AKSZ' designation indicates the Grade A accuracy, SC-70 package, and RoHS-compliant tape-and-reel packaging.
