LT1460KCS3-10#TRMPBF

Voltage Reference Overview

The LT1460KCS3-10#TRMPBF is a micropower precision series voltage reference manufactured by Analog Devices Inc. It provides a fixed output voltage of 10V with an initial accuracy tolerance of ±0.5%. The device operates within a commercial temperature range of 0°C to 70°C and features a maximum temperature coefficient of 50ppm/°C. It requires a minimum input-to-output differential voltage of 0.9V and supports a maximum supply current of 350µA. The component is housed in a compact 3-lead SOT-23 surface-mount package.

Voltage Reference Feature Summary

• Utilizes curvature compensation and trimmed thin-film resistors for high accuracy and low drift
• Capable of sourcing up to 20mA without requiring an external output compensation capacitor
• Includes reverse battery protection to prevent damage from incorrect polarity connections

Voltage Reference Applications

• Precision analog-to-digital converter (ADC) reference sources
• High-accuracy digital-to-analog converter (DAC) systems
• Handheld instruments and portable measurement devices
• Precision regulator applications

Voltage Reference Procurement Notes

Verify the specific ordering suffix #TRMPBF to confirm the tape-and-reel packaging format containing 500 pieces per reel. Ensure the K grade designation matches the required ±0.5% accuracy specification. Confirm the S3 package code corresponds to the SOT-23 form factor for PCB layout compatibility. Validate that the commercial temperature range meets the operational requirements of the target environment.

Voltage Reference Selection Notes

Select this part when a stable 10V reference is needed in space-constrained designs using the SOT-23 footprint. The K grade offers a balance of cost and performance suitable for general industrial applications. Consider the 50ppm/°C drift rate against environmental temperature variations. Verify that the 0.9V dropout voltage allows sufficient headroom from the system power supply.

Voltage Reference Part Context

This component belongs to the LT1460 family of micropower bandgap references, which combines high accuracy with low power dissipation. The series utilizes curvature compensation technology to achieve low temperature coefficients across operating ranges. The LT1460 architecture provides significant power advantages over traditional shunt references by eliminating the need for constant idle current draw.
