MAX6068BEUR

Overview

The MAX6068BEUR is a micropower, low-dropout voltage reference from Analog Devices Inc./Maxim Integrated. It provides a fixed 1.8V output with an initial accuracy of 0.17% and a temperature coefficient of 6 PPM/°C. The device operates within an input voltage range up to 12.6V and draws a typical supply current of 90 µA, with a maximum of 125 µA. It supports a maximum shunt current of 5 mA and functions reliably between -40°C and +85°C in a compact SOT-23-3 package.

Feature Summary

• Micropower operation with low quiescent current consumption
• High precision with tight initial accuracy and low temperature drift
• Low dropout capability for efficient power management
• High output current drive capability

Applications

• Portable instrumentation systems
• Battery-powered measurement devices
• Data acquisition systems requiring stable references
• Precision analog signal conditioning circuits

Procurement Notes

Verify the specific suffix (e.g., T for tape-and-reel) against your manufacturing requirements. Confirm RoHS compliance status via the official datasheet. Check current availability as distribution may be limited or restricted. Ensure the SOT-23-3 footprint matches your PCB design constraints before ordering.

Selection Notes

Select this component when a stable 1.8V reference is required with minimal power draw. The 0.17% accuracy suits high-precision applications. Consider the 12.6V max input for wide-range supply compatibility. The 5mA output current allows direct driving of moderate loads without external buffering.

Part Context

This part belongs to the MAX6068 series of precision voltage references. It is designed for applications demanding high stability and low power consumption. The series offers various output voltages and accuracies, with the BEUR variant providing 1.8V at 0.17% accuracy in a small surface-mount package suitable for space-constrained designs.

Replacement Considerations

Check for MAX6068AEUR+ for similar performance characteristics. Verify pinout compatibility with SOT-23-3 packages. Ensure replacement parts meet the same 1.8V output and 0.17% accuracy specifications. Confirm operating temperature ranges align with system requirements.
