LT1029CZ#PBF

Voltage Reference Overview

The LT1029CZ#PBF is a fixed 5V bandgap voltage reference IC manufactured by Analog Devices Inc. It operates in shunt mode with a typical output voltage of 5V and an initial accuracy of ±0.2%. The device requires a minimum shunt current of 700µA and features a maximum temperature coefficient of 20 ppm/°C. Designed for through-hole mounting, it utilizes the TO-92-3 package and functions within an operating temperature range of 0°C to 70°C.

Voltage Reference Feature Summary

• Fixed 5V bandgap reference architecture
• High initial accuracy of ±0.2%
• Operates in positive or negative shunt modes

Voltage Reference Applications

• Precision measurement systems
• Data acquisition circuits
• Instrumentation amplifiers

Voltage Reference Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance and RoHS adherence when sourcing from distributors. Confirm the TO-92-3 package style matches your PCB footprint requirements. Ensure the supplier provides valid traceability documentation for Analog Devices Inc. components to guarantee authenticity and quality standards.

Voltage Reference Selection Notes

Select this component when a stable 5V reference is required in a low-cost, small form factor. The TO-92-3 package suits through-hole assembly processes. Consider the 700µA minimum current requirement for biasing circuit design. Evaluate thermal performance within the 0°C to 70°C industrial range against application demands.

Voltage Reference Part Context

This part belongs to the LT1029 family of 5V bandgap references. It serves as a fundamental building block for analog signal conditioning. The series offers various package options including surface mount and through-hole configurations. Analog Devices continues production under the Linear Technology heritage.

Voltage Reference Replacement Considerations

LT1029CZ is the direct equivalent without the Pb-free suffix. Verify pinout compatibility before substitution. Other 5V shunt references may require different bias currents.
