LT1034IS8-2.5#TRPBF

Voltage Reference Overview

The LT1034IS8-2.5#TRPBF is a micropower dual shunt voltage reference manufactured by Analog Devices Inc., housed in an 8-SOIC surface-mount package. It provides fixed output voltages of 2.5V and 7V with an initial accuracy tolerance of ±1.6%. The device operates within a temperature range of -40°C to +85°C and features a temperature coefficient of 40ppm/°C. Key electrical specifications include a low noise performance of 6µVp-p from 0.1Hz to 10Hz, a maximum cathode current of 30 µA, and a load current capability of 20 mA.

Voltage Reference Feature Summary

• Dual-output architecture providing both 2.5V and 7V references within a single compact component
• Micropower design optimized for low quiescent current consumption applications
• Low-noise performance suitable for precision analog signal conditioning circuits

Voltage Reference Applications

• Precision data acquisition systems requiring stable reference sources
• Analog-to-digital converter (ADC) reference inputs
• Battery-powered instrumentation utilizing low-power components

Voltage Reference Procurement Notes

Verify the exact part number suffix against official Analog Devices documentation to confirm packaging type and RoHS compliance status. The #TRPBF suffix indicates tape-and-reel packaging. Confirm availability through authorized distributors as supply status may vary. Ensure the procurement channel is authorized to guarantee component authenticity and traceability.

Voltage Reference Selection Notes

Select this component when a dual-voltage reference is required in a space-constrained surface-mount design. Compare the ±1.6% initial accuracy and 40ppm/°C temperature coefficient against application requirements. Consider the 20 mA load current limit and 30 µA cathode current specifications for power budget calculations relative to alternative series or shunt references.

Voltage Reference Part Context

This component belongs to the LT1034 series of micropower dual references from Analog Devices. It shares the same functional core as other variants in the family but is distinguished by its specific 2.5V output voltage, 8-SOIC package, and tape-and-reel packaging configuration. It serves as a specialized solution for designs needing multiple reference levels without consuming additional board space.

Voltage Reference Replacement Considerations

LT1034IS8-2.5#TR is a direct substitute differing only in packaging format.
