LT1034BCZ-2.5#PBF

Voltage Reference Overview

The LT1034BCZ-2.5#PBF is a micropower dual voltage reference manufactured by Analog Devices Inc., housed in a TO-92-3 through-hole package. It provides two fixed output voltages: 2.5 V and 7 V. The device features an initial accuracy of 1% and a temperature coefficient of 20 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 functions without a shutdown mode and supports an ambient operating temperature range from 0°C to +70°C.

Voltage Reference Feature Summary

• Dual-output architecture providing both 2.5 V and 7 V references in a single compact package
• High precision performance characterized by 1% initial accuracy and low temperature drift
• Micropower design optimized for battery-powered applications with minimal quiescent current consumption

Voltage Reference Applications

• Precision analog-to-digital converter (ADC) reference sources
• Battery-operated instrumentation systems requiring stable voltage rails
• Data acquisition systems needing isolated reference potentials

Voltage Reference Procurement Notes

Verify the specific suffix and package type during procurement, as the LT1034 series includes various packages such as SOIC and TO-92. Confirm that the BCZ variant matches the required temperature coefficient and accuracy specifications for the target application. Check current availability status, as older components may have limited stock or require alternative sourcing strategies.

Voltage Reference Selection Notes

Select this component when a dual-reference solution is required in a through-hole form factor. The 20 PPM/°C temperature coefficient offers better thermal stability than standard industrial grades. Ensure the load current requirements fall within the 2 mA to 20 mA shunt current limits to maintain regulation accuracy.

Voltage Reference Part Context

This part belongs to the LT1034 family of micropower dual references from Analog Devices. Unlike surface-mount variants like the IS8 series, the BCZ designation indicates a TO-92-3 plastic transistor-style package suitable for through-hole mounting. The family is designed to replace discrete zener diode references with higher precision and lower power consumption.
