LT1034CZ-2.5#TRPBF

Voltage Reference Overview

The LT1034CZ-2.5#TRPBF is a micropower dual voltage reference IC manufactured by Analog Devices Inc., housed in a TO-92-3 package. It provides two fixed output voltages: 2.5V and 7V. The device features an initial accuracy of ±1% and a temperature coefficient of 20ppm/°C. It operates within a junction temperature range of -55°C to 125°C, with a maximum shunt current of 20mA and a minimum operating current of 2mA. The input voltage can reach up to 15V.

Voltage Reference Feature Summary

• Dual-output architecture providing both 2.5V and 7V references in a single component
• Micropower design optimized for low current consumption applications
• High precision performance with tight initial accuracy specifications

Voltage Reference Applications

• Precision analog-to-digital converter (ADC) reference sources
• Battery-powered instrumentation requiring stable voltage rails
• Data acquisition systems needing multiple reference levels

Voltage Reference Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging when sourcing. Confirm RoHS compliance status as manufacturing processes may evolve. Check for obsolescence notices or lifecycle changes directly from Analog Devices documentation before finalizing procurement plans.

Voltage Reference Selection Notes

Select this component when dual reference voltages are required in a compact through-hole package. Ensure the 20ppm/°C temperature coefficient meets system drift requirements. Verify that the 20mA maximum shunt current capability aligns with the load demands of the connected circuitry.

Voltage Reference Part Context

This part belongs to the LT1034 series of micropower dual references. It serves as a cost-effective alternative to using separate discrete voltage reference components. The TO-92-3 package allows for easy prototyping and through-hole PCB integration compared to surface-mount alternatives.

Voltage Reference Replacement Considerations

LT1034CZ-2.5#PBF offers identical electrical characteristics but utilizes bulk packaging instead of tape-and-reel.
