MX581TH

Overview

The MX581TH is a three-terminal, temperature-compensated bandgap voltage reference manufactured by Analog Devices Inc./Maxim Integrated. It provides a precision 10V output from an unregulated input voltage range of 12.5V to 30V. The device utilizes laser trimming to minimize initial error and temperature drift, achieving a maximum tolerance of ±10mV and a low temperature coefficient of 15ppm/°C. It features short-circuit protection, the ability to source and sink current with a 10mA output capability, and a low supply current of 1.0mA maximum.

Feature Summary

• Provides a stable 10V reference via a three-terminal package design
• Laser trimmed for high precision with minimal initial error and temperature drift
• Capable of sourcing and sinking output current up to 10mA
• Includes internal short-circuit protection mechanisms

Applications

• CMOS DAC Reference
• A/D Converter Reference
• Measurement Instrumentation
• Threshold Detectors
• Precision Analog Systems

Procurement Notes

Verify the specific suffix TH against official datasheets to confirm package type and military-grade qualification status. Confirm availability through authorized distributors as this component may have limited stock or be subject to special ordering constraints. Ensure compatibility with existing system input voltage ranges between 12.5V and 30V before procurement.

Selection Notes

Select this component when a high-precision 10V reference is required with minimal external component count. It is suitable for applications demanding low temperature drift and short-circuit protection. Consider the 1.0mA maximum supply current and 10mA output capability when designing power budgets and load requirements for the target analog circuitry.

Part Context

This part belongs to the MX58x series of high-precision voltage references from Maxim Integrated, now part of Analog Devices. The series includes variants such as the MX580 (2.5V) and MX581 (10V). These devices are designed for applications requiring stable reference voltages without the need for external trimming components, leveraging bandgap technology and laser trimming for accuracy.
