LT1460GCZ-5#PBF

Voltage Reference Overview

The LT1460GCZ-5#PBF is a micropower precision series voltage reference manufactured by Analog Devices Inc. It provides a fixed output voltage of 5 V with an initial accuracy of ±0.25%. The device operates within a commercial temperature range of 0°C to +70°C and features a maximum temperature coefficient of 25 ppm/°C. It utilizes curvature compensation and trimmed thin-film resistors for high stability. The component requires a minimum input-output differential of 0.9 V, supports a maximum input voltage of 20 V, and draws a typical supply current of 125 µA. It is housed in a 3-lead TO-92 plastic package.

Voltage Reference Feature Summary

• Curvature compensated bandgap architecture ensures low temperature drift and high output accuracy.
• Capacitive load stable operation eliminates the requirement for external output compensation capacitors.
• Reverse battery protection prevents current conduction and potential damage during incorrect polarity connections.

Voltage Reference Applications

• Precision regulators
• Handheld instruments
• A/D and D/A converters

Voltage Reference Procurement Notes

Verify the specific suffix GCZ corresponds to the TO-92 package and commercial temperature grade (0°C to 70°C) required for the design. Confirm that the ±0.25% accuracy and 25 ppm/°C temperature coefficient meet system specifications. Check availability status as distribution channels may indicate limited stock or restricted sales conditions for this specific part number.

Voltage Reference Selection Notes

Select this component when a fixed 5 V reference with moderate precision is needed in a through-hole TO-92 package. Ensure the application operates within the 0°C to 70°C commercial temperature range. Verify that the 125 µA supply current and 20 mA sourcing capability align with power budget and load requirements. Consider alternative packages if surface mount technology or wider industrial temperature ranges are necessary.

Voltage Reference Part Context

This part belongs to the LT1460 Micropower Precision Series Reference Family. The family offers various output voltages and accuracy grades across multiple package types including SO-8, MSOP-8, PDIP-8, SOT-23, and TO-92. The LT1460GCZ-5#PBF specifically represents the 5 V output variant with ±0.25% accuracy in the TO-92 form factor.

Voltage Reference Replacement Considerations

LT1460GIZ-5#PBF serves as a direct functional substitute offering identical electrical characteristics but rated for an extended industrial temperature range of –40°C to 85°C while maintaining the same TO-92 package.
