LT1460FCMS8-2.5#TRPBF

Voltage Reference Overview

The LT1460FCMS8-2.5#TRPBF is a micropower precision series voltage reference manufactured by Analog Devices Inc., housed in an 8-lead MSOP package. It provides a fixed output voltage of 2.5V with an initial accuracy tolerance of ±0.15%. The device operates within a commercial temperature range of 0°C to 70°C and features a maximum temperature coefficient of 25ppm/°C. It draws a typical supply current of 130µA for the 2.5V variant, with a maximum input voltage of 20V and a minimum dropout voltage of 0.9V.

Voltage Reference Feature Summary

• Utilizes curvature compensation and trimmed thin-film resistors to achieve high output accuracy and low drift.
• Capable of sourcing up to 20mA while maintaining excellent line regulation characteristics.
• Operates stably with capacitive loads without requiring an external output compensation capacitor.
• Includes reverse battery protection that prevents current conduction during reverse connections.

Voltage Reference Applications

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

Voltage Reference Procurement Notes

Verify the specific suffix TRPBF indicates tape and reel packaging when ordering. Confirm the FC grade matches the required 0.15% accuracy and 25ppm/°C temperature coefficient specifications. Ensure the MSOP-8 package form factor fits the target PCB layout constraints. Check for lead-free compliance status if required by assembly standards.

Voltage Reference Selection Notes

Select this component when a balance of micropower consumption and moderate precision is required for space-constrained designs. The MSOP-8 package offers a compact footprint suitable for dense layouts. Consider the 25ppm/°C drift specification against environmental temperature variations. Verify that the 20mA output current capability meets the load requirements of the downstream circuitry.

Voltage Reference Part Context

This part belongs to the LT1460 Micropower Precision Series Reference Family from Analog Devices. The family includes various packages such as SO-8, PDIP-8, TO-92, and SOT-23, with different accuracy grades ranging from 0.075% to 0.50%. The LT1460 series is designed to replace older shunt references by eliminating the need for current-setting resistors, thereby reducing power dissipation.
