LT1019IN8-10#PBF

Voltage Reference Overview

The LT1019IN8-10#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 10 V with an initial accuracy of 0.2% and a temperature coefficient of 20 PPM/C. The device operates within a supply voltage range up to 40 V, drawing a typical quiescent current of 650 uA and supporting a maximum shunt current of 10 mA. It functions reliably across an extended industrial temperature range from -40 C to +85 C.

Voltage Reference Feature Summary

• Provides stable 10 V reference via shunt architecture
• Ensures high precision with 0.2% initial accuracy
• Operates effectively in extended industrial temperature environments

Voltage Reference Applications

• Precision analog-to-digital converter (ADC) references
• Data acquisition system voltage standards
• Calibration equipment reference sources

Voltage Reference Procurement Notes

Verify the specific suffix IN8-10#PBF against official Analog Devices documentation to confirm the through-hole PDIP package and -40C to +85C operating range. Confirm RoHS compliance status directly with the manufacturer or authorized distributors, as availability may be restricted. Ensure the application circuit supports the required 10 mA maximum shunt current capability for proper regulation.

Voltage Reference Selection Notes

Select this component when a 10 V shunt reference is required for through-hole PCB designs. The -40C to +85C temperature range suits industrial applications better than commercial grades. Compare the 20 PPM/C temperature coefficient against stricter requirements; if lower drift is needed, consider the AC grade variants which offer improved stability at potentially higher costs.

Voltage Reference Part Context

This part belongs to the LT1019 series of precision shunt voltage references. Unlike series regulators, shunt references regulate by sinking current to ground, requiring a series resistor to limit current. The IN8 designation indicates the standard industrial grade version with through-hole packaging, distinct from the CN commercial grade or AC precision grade options available in the same family.

Voltage Reference Replacement Considerations

LT1019CN8-10#PBF offers identical electrical specifications but is rated for a commercial temperature range of 0 C to +70 C. LT1019ACN8-10#PBF provides superior 5 PPM/C temperature coefficient performance. Verify that any replacement maintains the 10 V output and PDIP-8 footprint compatibility.
