LT1009IS8#TRPBF

Voltage Reference Overview

The LT1009IS8#TRPBF is a shunt precision voltage reference manufactured by Analog Devices Inc., housed in an SOIC-8 surface-mount package. It provides a fixed output voltage of 2.5 V with an initial accuracy of 0.4%. The device operates within a temperature range of -40°C to +85°C and features a maximum temperature coefficient of 35 PPM/°C. Electrical specifications include a maximum input voltage of 35 V and a maximum shunt current of 10 mA. This component belongs to the LT1009 series and is classified under PMIC voltage references.

Voltage Reference Feature Summary

• Provides a stable 2.5 V reference voltage suitable for precision applications
• Features low temperature coefficient for consistent performance across operating ranges
• Designed as a shunt reference requiring minimal external components

Voltage Reference Applications

• Precision analog-to-digital converter (ADC) reference sources
• Data acquisition systems requiring stable voltage benchmarks
• Instrumentation circuits demanding high accuracy

Voltage Reference Procurement Notes

Verify the specific suffix against official documentation, as standard datasheets often list the tube variant (LT1009IS8#PBF). Confirm tape-and-reel availability directly with the manufacturer or authorized distributors, as stock status may vary. Ensure the part number matches the required packaging format for automated assembly processes before finalizing procurement orders.

Voltage Reference Selection Notes

Select this component when a fixed 2.5 V shunt reference is required in a compact SOIC-8 footprint. Consider the 0.4% initial accuracy and 35 PPM/°C temperature coefficient against system requirements. Verify that the 10 mA maximum shunt current capability meets the load demands of the target circuit design without exceeding thermal limits.

Voltage Reference Part Context

This part belongs to the LT1009 family of precision voltage references from Analog Devices. The family includes various output voltages and packages. The IS8 designation indicates the industrial temperature grade and SOIC-8 package type. The #TRPBF suffix denotes the tape-and-reel packaging option with lead-free compliance, distinguishing it from the tube-packaged version.

Voltage Reference Replacement Considerations

Consult official substitution guides for compatible shunt references. Verify pinout compatibility and electrical parameter alignment with potential alternatives.
