LT1034BCZ-1.2#PBF

Voltage Reference Overview

The LT1034BCZ-1.2#PBF is a dual-output shunt voltage reference from the LT1034 series, manufactured by Analog Devices Inc. It provides two fixed output voltages: 1.225 V and 7 V. The device is housed in a TO-92-3 package designed for through-hole mounting. It operates within a temperature range of 0°C to +70°C. The initial accuracy is specified at 1%, with a temperature coefficient of 40 PPM/°C. Maximum input voltage is 15 V, with a maximum shunt current of 20 mA and a minimum operating current of 2 mA.

Voltage Reference Feature Summary

• Dual-output architecture providing both precision low-voltage and auxiliary high-voltage references in a single component.
• Shunt regulation design suitable for applications requiring stable reference potentials without active control loops.

Voltage Reference Applications

• Precision analog-to-digital converter (ADC) reference inputs
• Microprocessor power supply monitoring circuits
• Instrumentation amplifier biasing

Voltage Reference Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance and tube packaging when sourcing. Confirm the BCZ grade matches the required 1% initial accuracy specification. Check manufacturer documentation for RoHS status updates as regulatory requirements evolve. Ensure the through-hole TO-92-3 package aligns with the target PCB footprint and assembly process capabilities.

Voltage Reference Selection Notes

Select this part when a compact through-hole solution is required for dual-reference needs. The 1.225 V output serves standard logic levels, while the 7 V output supports higher voltage rails. Verify that the 40 PPM/°C temperature coefficient meets system drift requirements. Consider the 20 mA maximum current limit for load driving capabilities.

Voltage Reference Part Context

This component belongs to the LT1034 family of dual-output voltage references. It shares functional characteristics with other variants like the LT1034CS8-1.2#PBF but differs in package type and mounting style. The BCZ designation specifies the commercial temperature range and accuracy grade within the broader product line.

Voltage Reference Replacement Considerations

LT1034CS8-1.2#PBF offers identical electrical performance in an SOIC-8 surface-mount package. Substitution requires PCB layout modification to accommodate the different physical footprint and pinout configuration.
