LT1019ACN8-10#PBF

Voltage Reference Overview

The LT1019ACN8-10#PBF is a shunt precision voltage reference from Analog Devices, housed in an 8-pin PDIP package. It provides a fixed output voltage of 10 V with an initial accuracy of 0.05% and a temperature coefficient of 5 PPM/C. The device operates within a supply voltage range up to 40 V and supports a maximum shunt current of 10 mA. It functions reliably across a commercial temperature range of 0°C to +70°C, drawing a typical supply current of 650 uA.

Voltage Reference Feature Summary

• Delivers high-precision voltage regulation with tight initial accuracy tolerances for critical analog circuits.
• Features ultra-low temperature drift characteristics to maintain stability across varying thermal conditions.
• Utilizes a shunt reference topology suitable for series regulator applications and high-voltage inputs.

Voltage Reference Applications

• High-resolution data acquisition systems requiring stable reference voltages
• Precision instrumentation amplifiers and signal conditioning circuits
• Calibration equipment and test measurement devices

Voltage Reference Procurement Notes

Verify the specific suffix ACN8-10 against the official datasheet to confirm the 0.05% accuracy grade and 5 PPM/C temperature coefficient. Ensure the PDIP-8 package matches the target PCB footprint. Confirm RoHS compliance status through the manufacturer's latest documentation before finalizing procurement specifications.

Voltage Reference Selection Notes

Select this component when superior long-term stability and low temperature drift are required compared to standard 0.2% accuracy variants. The 10 V output level is appropriate for high-voltage single-supply systems. Consider the PDIP-8 package constraints for through-hole assembly processes and verify that the 10 mA load capability meets the circuit's current sink requirements.

Voltage Reference Part Context

This part belongs to the LT1019 family of precision shunt references, designed as drop-in replacements for older Zener-based solutions. The 'AC' designation indicates the highest accuracy grade within the CN8 product line, offering tighter performance bounds than the standard 'CN8' version while maintaining the same physical form factor and pinout compatibility.

Voltage Reference Replacement Considerations

LT1019CN8-10#PBF offers lower accuracy (0.2%) but shares the same package and electrical interface. LT1019IN8-10#PBF provides industrial temperature range (-40°C to +85°C) with 0.2% accuracy. Verify if the stricter 0.05% tolerance of the AC variant is necessary for the specific application design margins.
