LT1034CS8-2.5#PBF

Voltage Reference Overview

The LT1034CS8-2.5#PBF is a dual shunt voltage reference IC manufactured by Analog Devices Inc., housed in an 8-SOIC surface-mount package. It provides two fixed output voltages: 2.5V and 7V. 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 functions across a commercial temperature range from 0°C to +70°C.

Voltage Reference Feature Summary

• Dual-output architecture providing independent 2.5V and 7V references within a single compact package.
• Shunt regulation design suitable for low-power applications requiring stable reference voltages.

Voltage Reference Applications

• Precision analog-to-digital converter (ADC) reference sources
• Microprocessor power supply monitoring circuits
• Data acquisition system calibration

Voltage Reference Procurement Notes

Verify the specific suffix #PBF indicates lead-free tube packaging when sourcing. Confirm that the CS8 variant meets the required commercial temperature range specifications for the intended application environment. Ensure compatibility with standard SOIC-8 footprint layouts during PCB design validation.

Voltage Reference Selection Notes

Select this component when dual reference outputs are required in a space-constrained design. Compare against the IS8 series if extended industrial temperature ranges or tighter initial accuracy tolerances are necessary for the specific operational requirements.

Voltage Reference Part Context

This part belongs to the LT1034 family of micropower dual voltage references. It shares functional similarities with other variants like the LT1034CS8-1.2#PBF but differs in output voltage levels. The series is designed for applications needing multiple stable voltage rails without separate discrete components.

Voltage Reference Replacement Considerations

LT1034IS8-2.5#PBF offers extended temperature range and higher accuracy. LT1034BCZ-2.5#PBF provides through-hole packaging options with improved temperature coefficients.
