LT1019IS8-2.5#PBF

Voltage Reference Overview

The LT1019IS8-2.5#PBF is a precision shunt voltage reference from Analog Devices, housed in an 8-pin SOIC package. It provides a fixed output voltage of 2.5 V with an initial accuracy of ±0.2%. The device operates within a supply voltage range of 4 V to 40 V and draws a maximum supply current of 1.5 mA. It features a temperature coefficient of 20 ppm/°C and supports a maximum cathode current of 10 mA. The component functions reliably across an industrial temperature range of -40°C to +85°C.

Voltage Reference Feature Summary

• Provides stable precision voltage referencing through a shunt architecture
• Maintains high accuracy with low temperature drift characteristics
• Operates efficiently with minimal quiescent current consumption

Voltage Reference Applications

• Precision analog-to-digital converter (ADC) reference sources
• Digital-to-analog converter (DAC) voltage references
• High-resolution measurement instrumentation circuits
• Battery-powered systems requiring stable reference voltages

Voltage Reference Procurement Notes

Verify the specific suffix IS8 confirms the industrial temperature grade and SOIC-8 surface-mount package configuration. Ensure the #PBF designation indicates lead-free compliance for your assembly requirements. Confirm availability status as distribution channels may report limited stock or discontinuation notices for this specific part number variant.

Voltage Reference Selection Notes

Select this component when a fixed 2.5 V reference is required with tight initial tolerance specifications. The shunt topology necessitates a series dropping resistor to regulate current flow. Consider the 20 ppm/°C temperature coefficient against application thermal stability needs. Verify that the 10 mA maximum cathode current capability meets the load requirements without exceeding power dissipation limits.

Voltage Reference Part Context

This part belongs to the LT1019 family of precision shunt voltage references designed for high-performance applications. The IS8 suffix denotes the industrial temperature range (-40°C to +85°C) and the 8-lead SOIC surface-mount package. The 2.5V output option complements other available voltages like 2.5V, 5V, and 10V within the same series.
