LT1034BCZ-1.2#TRPBF

Voltage Reference Overview

The LT1034BCZ-1.2#TRPBF is a micropower dual voltage reference IC manufactured by Analog Devices Inc. It integrates two precision series references within a single TO-92-3 package, providing fixed output voltages of 1.225 V and 7 V. The device features an initial accuracy of 1% and operates with a maximum shunt current of 20 mA. Designed for through-hole mounting, it functions within a commercial temperature range of 0°C to +70°C. The component utilizes a reel packaging format for automated assembly processes.

Voltage Reference Feature Summary

• Integrates two independent precision series voltage references in a compact three-lead package
• Provides stable fixed output voltages suitable for low-power analog circuits
• Operates with minimal quiescent current consumption for battery-powered applications

Voltage Reference Applications

• Portable instrumentation requiring multiple reference levels
• Battery-operated measurement systems
• Low-power data acquisition front-ends

Voltage Reference Procurement Notes

Verify the specific suffix #TRPBF against official manufacturer documentation to confirm tape-and-reel packaging and lead-free compliance status. Confirm that the BCZ grade meets the required 1% initial accuracy specifications for your design. Ensure the through-hole TO-92-3 footprint aligns with your PCB layout constraints before finalizing procurement.

Voltage Reference Selection Notes

Select this component when a dual-reference solution is required in a through-hole package to save board space compared to discrete components. The 1.225 V output serves as a standard bandgap reference, while the 7 V auxiliary output can bias other circuit stages. Verify that the 20 mA maximum shunt current capability satisfies the load requirements of your application without exceeding thermal limits.

Voltage Reference Part Context

This part belongs to the LT1034 family of micropower dual voltage references from Analog Devices. The family offers various output combinations and accuracy grades across different packages. The BCZ variant specifically denotes the through-hole TO-92-3 form factor with commercial temperature rating, distinguishing it from SOIC or industrial grade alternatives.
