LT580MH

Voltage Reference Overview

The LT580MH is a precision shunt voltage reference IC manufactured by Analog Devices Inc. It provides a fixed output voltage of 2.5V with a tolerance of ±0.4%. The component utilizes a TO-52-3 metal can package and supports through-hole mounting. It belongs to the LT580X series within the PMIC - Power Management ICs category.

Voltage Reference Feature Summary

• Precision shunt regulation architecture
• Fixed 2.5V output capability
• ±0.4% initial accuracy tolerance

Voltage Reference Applications

• High-precision analog-to-digital converter (ADC) references
• Data acquisition systems requiring stable voltage sources
• Calibration equipment needing low-drift references

Voltage Reference Procurement Notes

Verify current availability status as the LT580MH is listed as obsolete or end-of-life. Confirm lead times and final purchase dates with authorized distributors. Ensure compliance with RoHS directives if required for specific manufacturing environments. Check for valid replacement components before procurement planning.

Voltage Reference Selection Notes

Select this component when a fixed 2.5V precision reference is required in a through-hole metal can package. Consider the ±0.4% tolerance for applications demanding high accuracy. Evaluate thermal performance and long-term stability requirements against the datasheet specifications. Verify compatibility with existing PCB footprints designed for TO-52-3 packages.

Voltage Reference Part Context
