LT1034IS8-2.5#PBF

Voltage Reference Overview

The LT1034IS8-2.5#PBF is a micropower dual 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, with an initial accuracy of ±1.6%. The device operates within a temperature range of -40°C to +85°C and features a temperature coefficient of 40ppm/°C. It draws a cathode current of 30 µA and supports a maximum output current of 20 mA.

Voltage Reference Feature Summary

• Dual-output architecture providing both 2.5V and 7V references in a single component
• Micropower operation designed for low current consumption applications
• Shunt regulator configuration suitable for precision voltage referencing

Voltage Reference Applications

• Precision analog-to-digital converter (ADC) reference sources
• Data acquisition systems requiring stable voltage baselines
• Battery-powered instrumentation circuits

Voltage Reference Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliant packaging when sourcing this component. Confirm that the SOIC-8 package matches your PCB footprint requirements. Check manufacturer documentation for RoHS compliance status and ensure the operating temperature range meets your environmental specifications before finalizing procurement decisions.

Voltage Reference Selection Notes

Select this part when a dual-voltage reference is required to minimize board space and component count. The 2.5V output serves as a primary reference while the 7V auxiliary output can bias other circuit stages. Ensure input voltage remains within the 15V maximum limit and maintain shunt current between 2mA and 20mA for optimal regulation performance.

Voltage Reference Part Context

This component belongs to the LT1034 series of micropower dual references from Analog Devices. It shares functional similarities with variants like the LT1034CS8-1.2#PBF but differs in output voltage levels and accuracy grades. The IS8 designation specifies the industrial temperature range and SOIC-8 package type, distinguishing it from commercial grade or through-hole alternatives.

Voltage Reference Replacement Considerations

LT1034IS8-2.5#TRPBF is a direct substitute offering identical electrical characteristics but supplied in tape-and-reel packaging instead of tube.
