LT1461CCS8-4#PBF

Voltage Reference Overview

The LT1461CCS8-4#PBF is a micropower precision low dropout series voltage reference manufactured by Analog Devices Inc. It provides a fixed output voltage of 4.096V 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 high output drive capability up to 50mA.

Voltage Reference Feature Summary

• Advanced curvature compensation techniques ensure low temperature drift and high stability.
• Integrated shutdown function allows system power down and load current switching.
• Thermal limiting protects the component from overload conditions.
• Trimmed precision thin-film resistors achieve high output accuracy.

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 when ordering. Confirm the CCS8 grade matches the required 0.08% accuracy and 12ppm/°C drift specifications for the target application. Ensure the commercial temperature range (0°C to 70°C) aligns with environmental constraints. Cross-reference the datasheet revision C for any updates to electrical characteristics or package dimensions before finalizing procurement.

Voltage Reference Selection Notes

Select this part when a stable 4.096V reference is needed with moderate precision requirements. The CCS8 grade offers a balance between cost and performance, suitable for general-purpose applications where ±0.08% accuracy is sufficient. Consider the 35µA supply current for battery-operated devices. Verify that the SO-8 package fits the PCB layout constraints and that the thermal dissipation remains within safe limits during operation.
