LT1019AIS8-2.5#TRPBF

Voltage Reference Overview

The LT1019AIS8-2.5#TRPBF is a precision shunt voltage reference from Analog Devices, providing a fixed 2.5V output with an initial accuracy of ±0.05% and a temperature coefficient of 10ppm/°C. It operates within an input voltage range of 4V to 40V, drawing a typical supply current of 650µA and supporting up to 10mA cathode current. The device features low noise characteristics, specified at 2.5ppm peak-to-peak (0.1Hz to 10Hz) and 2.5ppm RMS (10Hz to 1kHz). Designed for surface-mount applications, it is housed in an 8-SOIC package and functions reliably across an industrial temperature range of -40°C to +85°C.

Voltage Reference Feature Summary

• Delivers high-precision voltage regulation with ultra-low initial tolerance and minimal thermal drift for critical analog signal chains.
• Integrates low-noise performance suitable for sensitive measurement systems requiring stable reference potentials under varying conditions.
• Supports wide input voltage ranges and substantial load currents while maintaining efficient power consumption profiles.

Voltage Reference Applications

• High-resolution data acquisition systems
• Precision instrumentation amplifiers
• Calibration equipment references

Voltage Reference Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging when sourcing components. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the selected variant matches the required operating temperature range and accuracy class for the intended application environment.

Voltage Reference Selection Notes

Select this component when stringent accuracy requirements demand better than ±0.1% initial tolerance and superior temperature stability compared to standard references. Consider the 8-SOIC package constraints and verify that the 10mA maximum cathode current aligns with the circuit's biasing needs without exceeding thermal limits.

Voltage Reference Part Context

This part belongs to the LT1019 family of precision shunt voltage references, known for combining low noise with high accuracy. The 'AI' grade denotes tighter initial accuracy specifications compared to commercial grades, while the 'S8' suffix identifies the surface-mount SOIC-8 physical footprint used in compact electronic designs.

Voltage Reference Replacement Considerations

LT1019AIS8-2.5#PBF offers identical electrical specifications but utilizes tube packaging instead of tape-and-reel format.
