LT1461BIS8-3#PBF

Voltage Reference Overview

The LT1461BIS8-3#PBF is a micropower precision low dropout series voltage reference from Analog Devices. It provides a fixed 3V output with an initial accuracy of ±0.06% and a maximum temperature coefficient of 7ppm/°C over the industrial range. The device operates with a supply current of 35µA typical and supports up to 100mA output drive current. It functions within an input voltage range of 3.5V to 20V and is housed in an 8-lead SOIC package.

Voltage Reference Feature Summary

• Combines high accuracy with low drift using advanced curvature compensation and trimmed thin-film resistors.
• Features a power shutdown capability to switch full load currents and enable system power down.
• Includes thermal limiting protection to safeguard against overload conditions.

Voltage Reference Applications

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

Voltage Reference Procurement Notes

Verify the specific suffix configuration matches the required temperature grade and packaging format. Confirm that the component meets RoHS compliance standards for the intended deployment region. Ensure the ordering information aligns with the specified industrial temperature range and output voltage tolerance requirements before finalizing procurement.

Voltage Reference Selection Notes

Select this part when a fixed 3V reference with ±0.06% initial accuracy is required. It is suitable for applications needing low quiescent current alongside moderate output drive capabilities. Consider the 8-lead SOIC package constraints and verify that the input voltage differential remains within the specified dropout limits for the expected load conditions.
