LT1034BIZ-1.2#TRPBF

Voltage Reference Overview

The LT1034BIZ-1.2#TRPBF is a micropower dual voltage reference manufactured by Analog Devices Inc., housed in an 8-lead SOIC surface-mount package. It provides two fixed output voltages: a primary precision reference of 1.225 V and an auxiliary reference of 7 V. The device features an initial accuracy of 1% and a temperature coefficient of 40 ppm/°C. It operates within a supply voltage range up to 15 V, with a maximum shunt current of 20 mA and a minimum operating current of 2 mA. The component supports an industrial temperature range from -40°C to +85°C.

Voltage Reference Feature Summary

• Dual-output architecture providing both a 1.225 V precision reference and a 7 V auxiliary reference within a single compact package.
• Micropower design optimized for low current consumption applications while maintaining stable voltage regulation.
• Industrial-grade thermal performance ensuring reliable operation across extended temperature ranges.

Voltage Reference Applications

• Precision analog-to-digital converter (ADC) reference sources
• Microprocessor power monitoring circuits
• Data acquisition systems requiring stable voltage baselines

Voltage Reference Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging compatible with automated assembly processes. Confirm that the B grade designation meets the required 1% initial accuracy specification for your application. Ensure the SOIC-8 footprint matches your PCB layout constraints. Check RoHS compliance status against regional regulatory requirements before finalizing procurement orders.

Voltage Reference Selection Notes

Select this component when a dual-voltage solution is required to minimize board space compared to using separate discrete references. The 1.225 V output serves as a standard low-voltage reference, while the 7 V auxiliary output can bias other circuit stages. Consider the 40 ppm/°C temperature coefficient if high thermal stability is critical. Verify that the 20 mA maximum shunt current capability aligns with the load requirements of your design.

Voltage Reference Part Context

This part belongs to the LT1034 series of micropower dual voltage references. It shares functional characteristics with other variants in the family but differs in package type, temperature grade, and shipping configuration. The LT1034 series is designed to replace older, larger dual-reference solutions, offering improved integration and lower power consumption for portable and battery-operated electronic systems.

Voltage Reference Replacement Considerations

LT1034BIZ-1.2#PBF offers identical electrical specifications in tube packaging instead of tape-and-reel format.
