LT1461BIS8-2.5#PBF

Voltage Reference Overview

The LT1461BIS8-2.5#PBF is a micropower precision low dropout series voltage reference manufactured by Analog Devices Inc. It provides a fixed 2.5V output with an initial accuracy of ±0.06% and a maximum temperature coefficient of 7ppm/°C. The device operates within an industrial temperature range of –40°C to 85°C and draws a typical supply current of 35µA. It features a shutdown pin for power management, thermal limiting protection, and high output drive capability.

Voltage Reference Feature Summary

• Advanced curvature compensation techniques ensure low temperature drift and high output accuracy.
• Integrated shutdown feature allows switching full load currents and enables system power down modes.
• Thermal shutdown protects the component from overload conditions and excessive junction temperatures.

Voltage Reference Applications

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

Voltage Reference Procurement Notes

Verify the specific suffix #PBF indicates lead-free tube packaging when sourcing. Confirm the IS8 designation corresponds to the industrial temperature grade (-40°C to 85°C) rather than commercial or high-grade variants. Ensure compatibility with 8-lead SOIC footprint requirements during procurement planning.

Voltage Reference Selection Notes

Select this part for applications requiring low quiescent current alongside moderate output drive capabilities. The 7ppm/°C temperature coefficient suits general precision needs where extreme stability is not critical. Consider the shutdown functionality if power conservation in standby modes is required for the target system design.

Voltage Reference Part Context

This component belongs to the LT1461 family of micropower precision low dropout series voltage references. The family utilizes trimmed precision thin-film resistors and advanced bandgap architectures. Other variants in the series offer different output voltages and accuracy grades, sharing similar package and functional characteristics.

Voltage Reference Replacement Considerations

LT1461BIS8-2.5#TRPBF serves as the tape and reel equivalent for automated assembly processes while maintaining identical electrical specifications and performance characteristics.
