LT1019ACN8-2.5#PBF

Voltage Reference Overview

The LT1019ACN8-2.5#PBF is a shunt precision voltage reference manufactured by Analog Devices Inc., housed in an 8-pin PDIP package. It provides a fixed output voltage of 2.5V with an initial accuracy of ±0.05% and a temperature coefficient of 5 ppm/°C. The device operates within an input voltage range of 6.5V to 40V, supporting a maximum shunt current of 10 mA and a minimum cathode current of 800 µA. Typical supply current is 650 µA, with a maximum of 1.5 mA. It functions reliably across a commercial temperature range of 0°C to +70°C.

Voltage Reference Feature Summary

• Delivers high-precision voltage regulation with ultra-low temperature drift characteristics for stable reference performance.
• Features low noise output suitable for sensitive analog signal processing and data conversion applications.
• Provides robust load and line regulation capabilities within a compact through-hole packaging format.

Voltage Reference Applications

• High-resolution digital-to-analog converters requiring precise reference voltages
• Precision measurement instrumentation and sensor signal conditioning circuits
• Data acquisition systems demanding stable voltage references under varying thermal conditions

Voltage Reference Procurement Notes

Verify the specific suffix designation to ensure the correct output voltage and accuracy grade are selected, as variations exist within the LT1019 family. Confirm that the PDIP-8 package aligns with the target PCB layout requirements. Check for RoHS compliance status and availability constraints, as distribution channels may report limited stock or regional shipping restrictions for this component.

Voltage Reference Selection Notes

Select this component when a 2.5V shunt reference with ±0.05% initial accuracy and 5 ppm/°C temperature coefficient is required. Ensure the application circuit can maintain the minimum cathode current of 800 µA while staying within the 10 mA maximum limit. Verify that the operating environment falls within the 0°C to +70°C commercial temperature range and that the input voltage remains between 6.5V and 40V.

Voltage Reference Part Context

This part belongs to the LT1019 series of precision shunt voltage references from Analog Devices. It shares the same core architecture and pinout as other variants in the family, differing primarily in output voltage and accuracy grade. The CN8 suffix indicates a standard plastic dual in-line package, distinguishing it from surface-mount SOIC options like the CS8 variant.
