LT1461CCS8-2.5#PBF

Voltage Reference Overview

The LT1461CCS8-2.5#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 ±0.08% and a maximum temperature coefficient of 12ppm/°C. The device operates within a commercial temperature range of 0°C to 70°C and draws a typical supply current of 35µA. It features a shutdown pin for power management, thermal limiting protection, and supports up to 50mA output drive current.

Voltage Reference Feature Summary

• Combines high accuracy and low drift with micropower consumption
• Includes a dedicated shutdown pin for system power control
• Features thermal limiting to protect against overload conditions

Voltage Reference Applications

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

Voltage Reference Procurement Notes

Verify the specific suffix #PBF indicates lead-free finish and tube packaging. Confirm the CCS8 designation matches the required accuracy grade (±0.08%) and temperature range (0°C to 70°C). Ensure the 2.5V output variant aligns with circuit requirements. Check for automotive qualified alternatives if wider temperature ranges are needed.

Voltage Reference Selection Notes

Select this component when a fixed 2.5V reference with ±0.08% initial accuracy is required. It is suitable for applications needing low quiescent current around 35µA while maintaining high output drive capability. Consider the 12ppm/°C temperature coefficient for stability needs. Verify that the 0°C to 70°C commercial temperature range meets environmental specifications.

Voltage Reference Part Context

This part belongs to the LT1461 family of micropower precision low dropout series voltage references. The family utilizes advanced curvature compensation and trimmed precision thin-film resistors. Other variants in the series offer different output voltages including 3V, 3.3V, 4.096V, and 5V, as well as varying accuracy grades and industrial/high-temperature options.
