LT1460EIN8-2.5#PBF

Voltage Reference Overview

The LT1460EIN8-2.5#PBF is a micropower precision series voltage reference manufactured by Analog Devices Inc., housed in an 8-lead plastic DIP package. It provides a fixed output voltage of 2.5V with an initial accuracy tolerance of ±0.125%. The device operates within an industrial temperature range of –40°C to 85°C and features a maximum temperature coefficient of 20ppm/°C. Key electrical specifications include a maximum supply current of 130µA for the 2.5V variant, a minimum guaranteed output sourcing current of 20mA, and a minimum input-to-output differential voltage of 0.9V.

Voltage Reference Feature Summary

• Curvature compensation combined with trimmed precision thin-film resistors ensures high output accuracy and low drift across the operating temperature range.
• Capacitive load stability without requiring external output compensation capacitors, facilitating fast settling times and reduced printed circuit board space requirements.
• Reverse battery protection prevents current conduction during reverse connections, safeguarding the component from damage.

Voltage Reference Applications

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

Voltage Reference Procurement Notes

Verify that the specific ordering suffix EIN8 corresponds to the Industrial temperature grade (–40°C to 85°C) and the 8-lead PDIP package configuration. Confirm compliance with lead-free finish standards as indicated by the #PBF designation. Ensure the selected part matches the required 2.5V output voltage option for the intended application design.

Voltage Reference Selection Notes

Select this component when an industrial temperature range is required alongside high precision. The EIN8 suffix denotes the –40°C to 85°C grade with a 20ppm/°C maximum temperature coefficient and ±0.125% initial accuracy. This differs from the commercial ACN8 grade which offers tighter accuracy but a narrower temperature range. Verify that the 20mA minimum output current meets the load requirements.

Voltage Reference Part Context

This component belongs to the LT1460 Micropower Precision Series Reference Family. The family utilizes bandgap technology to combine high accuracy with low power dissipation. Variants are available in multiple packages including SO-8, MSOP-8, PDIP-8, TO-92, and SOT-23, offering flexibility for different board space and thermal constraints.
