LT1460BIS8-5#TRPBF

Voltage Reference Overview

The LT1460BIS8-5#TRPBF is a micropower precision series voltage reference from Analog Devices, featuring a 5V output with ±0.1% initial accuracy and a maximum temperature coefficient of 10ppm/°C. It operates within an industrial temperature range of -40°C to +85°C in an 8-lead SOIC package. The device draws a typical supply current of 175µA and supports up to 20mA load current. Key electrical parameters include a line regulation of 35ppm/V and a dropout voltage of 1.4V at 10mA.

Voltage Reference Feature Summary

• Utilizes curvature compensation and trimmed thin-film resistors for high accuracy and low drift
• Operates stably with capacitive loads without requiring an external output compensation capacitor
• Provides reverse battery protection by preventing current conduction during reverse connections

Voltage Reference Applications

• Precision regulators
• A/D and D/A converters
• Handheld instruments
• Hard disk drives

Voltage Reference Procurement Notes

Verify the specific ordering suffix #TRPBF confirms tape and reel packaging and lead-free finish. Confirm the 'I' grade designation matches the required -40°C to +85°C industrial temperature range. Ensure the 'S8' package code corresponds to the 8-lead plastic SOIC footprint required for your PCB layout.

Voltage Reference Selection Notes

Select this component when low power consumption is critical alongside high precision. The series architecture offers lower dissipation than shunt references by eliminating the need for a constant current-setting resistor. Verify that the input voltage differential meets the minimum requirement of 0.9V to ensure proper regulation under all operating conditions.

Voltage Reference Part Context

This part belongs to the LT1460 Micropower Precision Series Reference Family. It shares core bandgap technology with variants offering different voltages (2.5V, 10V) and accuracies. The family is designed to replace older shunt references in applications demanding improved battery life and compact form factors.
