LT1019IS8-2.5#TRPBF

Voltage Reference Overview

The LT1019IS8-2.5#TRPBF is a precision shunt voltage reference manufactured by Analog Devices Inc., featuring a fixed output of 2.5 V with an initial accuracy of ±0.2%. It operates within a supply voltage range of 4 V to 40 V and draws a maximum quiescent current of 1.5 mA, with a minimum cathode current requirement of 800 µA. The device exhibits a temperature coefficient of 20 ppm/°C and low noise characteristics of 2.5 ppmp-p (0.1 Hz to 10 Hz). Packaged in an 8-SOIC surface-mount format, it supports an industrial operating temperature range from -40°C to +85°C.

Voltage Reference Feature Summary

• Provides stable 2.5 V reference via shunt architecture
• Ensures high precision with ±0.2% initial accuracy
• Maintains stability across wide temperature variations

Voltage Reference Applications

• Precision analog-to-digital converter references
• High-resolution digital-to-analog converter biasing
• Calibration standards for measurement equipment

Voltage Reference Procurement Notes

Verify the specific suffix #TRPBF confirms tape-and-reel packaging and lead-free compliance. Confirm the IS8 grade matches the required -40°C to +85°C industrial temperature range. Ensure input voltage exceeds the 4 V minimum while staying below the 40 V absolute maximum rating. Validate that circuit design maintains at least 800 µA cathode current for proper regulation.

Voltage Reference Selection Notes

Select this component when a fixed 2.5 V reference is required with tight initial tolerance. The industrial temperature grade suits applications outside commercial limits. Verify power dissipation capabilities within the SOIC package against expected load currents. Consider the 20 ppm/°C drift if extreme thermal stability is necessary for the target application.

Voltage Reference Part Context

This part belongs to the LT1019 series of precision shunt voltage references. It shares architectural similarities with other variants like the LT1019CS8-2.5#TRPBF but differs in temperature grading and packaging configuration. The series is designed for applications demanding low noise and high long-term stability without requiring external trimming components.

Voltage Reference Replacement Considerations

LT1019CS8-2.5#TRPBF offers identical electrical performance but is rated for commercial temperature ranges only.
