LT1019IS8-5#TRPBF

Voltage Reference Overview

The LT1019IS8-5#TRPBF is a precision shunt voltage reference from Analog Devices, housed in an 8-SOIC surface-mount package. It provides a fixed 5 V output with an initial accuracy of ±0.2% and a temperature coefficient of 20 ppm/°C. The device operates within a supply voltage range of 6.5 V to 40 V, requiring a minimum cathode current of 800 µA and supporting a maximum shunt current of 10 mA. Operating current is typically 650 µA, with a maximum of 1.5 mA. It functions reliably across an industrial temperature range of -40°C to +85°C.

Voltage Reference Feature Summary

• Delivers high-precision 5 V reference output with tight initial accuracy tolerance.
• Features low temperature coefficient for stable performance across wide thermal ranges.
• Designed as a shunt reference requiring minimal operating current for efficient power usage.

Voltage Reference Applications

• High-resolution analog-to-digital converter (ADC) reference sources
• Precision data acquisition systems
• Calibration equipment requiring stable voltage standards

Voltage Reference Procurement Notes

Verify the suffix #TRPBF confirms tape-and-reel packaging and lead-free compliance before ordering. Confirm the IS8 variant meets the required -40°C to +85°C industrial temperature specifications. Ensure input voltage remains above 6.5 V to maintain regulation. Check RoHS status documentation for environmental compliance requirements specific to your manufacturing process.

Voltage Reference Selection Notes

Select this component when a fixed 5 V precision reference is needed in a compact SOIC-8 footprint. It is suitable for applications demanding low drift and high accuracy without active shutdown control. Consider the 10 mA load capability for driving subsequent circuit stages directly. Verify that the series configuration fits within the available headroom of the system power supply.

Voltage Reference Part Context

This part belongs to the LT1019 family of precision shunt references manufactured by Analog Devices. It shares core architectural features with other variants in the series but differs in output voltage and packaging. The IS8 designation indicates the industrial temperature grade and surface-mount SOIC-8 form factor, distinguishing it from commercial or through-hole alternatives.
