LT1460MHS8-2.5#PBF

Voltage Reference Overview

The LT1460MHS8-2.5#PBF is a micropower precision series voltage reference manufactured by Analog Devices Inc., housed in an 8-lead plastic SO package. It provides a fixed output voltage of 2.5V with a maximum initial accuracy of ±0.20%. The device operates within a temperature range of –40°C to 125°C and features a maximum temperature coefficient of 50ppm/°C over the full operating range. It supports a minimum output current of 20mA, draws a typical supply current of 130µA for the 2.5V version, and requires a minimum input-to-output differential voltage of 0.9V.

Voltage Reference Feature Summary

• Utilizes curvature compensation and trimmed thin-film resistors to achieve high output accuracy and low drift.
• Capable of sourcing up to 20mA while maintaining excellent line regulation characteristics.
• Operates stably with capacitive loads without requiring an external output compensation capacitor.
• Includes reverse battery protection that prevents current conduction during reverse connections.

Voltage Reference Applications

• Handheld Instruments
• Precision Regulators
• A/D and D/A Converters
• Power Supplies

Voltage Reference Procurement Notes

Verify the specific suffix MHS8 against the manufacturer's ordering information to confirm the industrial/high-temperature grade (–40°C to 125°C) and SO-8 package type. Ensure the lead-free finish (#PBF) matches environmental compliance requirements. Confirm availability status as distribution channels may list limited stock or obsolescence notices for this specific temperature grade variant.

Voltage Reference Selection Notes

Select this component when an extended operating temperature range up to 125°C is required alongside precision voltage referencing. The MHS8 designation indicates a higher temperature coefficient compared to commercial grades, suitable for harsh environments. Consider the 20mA sourcing capability and lack of output capacitor requirement for space-constrained designs needing fast settling times.

Voltage Reference Part Context
