REF102AUG4

Overview

The Texas Instruments REF102AUG4 is a precision series voltage reference IC housed in an 8-SOIC package. It provides a fixed output voltage of 10V with a tight tolerance of ±0.1%. The device operates within an input voltage range of 11.4V to 36V and draws a supply current of 1.4mA. It supports a maximum output current of 10mA. Key performance metrics include a temperature coefficient of 10ppm/°C and low noise of 5µVp-p from 0.1Hz to 10Hz. The component functions reliably across an operating temperature range of -25°C to 85°C.

Feature Summary

• Provides high-precision fixed voltage output with minimal drift over temperature variations
• Features ultra-low noise characteristics suitable for sensitive analog signal processing
• Integrated internal compensation simplifies circuit design by minimizing external components

Applications

• High-resolution data acquisition systems
• Precision measurement instrumentation
• Calibration equipment requiring stable reference voltages

Procurement Notes

Verify the suffix 'G4' indicates specific manufacturing or packaging updates compared to the base REF102AU part number, as this may affect pinout compatibility or physical dimensions. Confirm RoHS compliance status and moisture sensitivity level (MSL 2) requirements for your assembly process. Ensure the 8-SOIC footprint matches your PCB layout constraints before finalizing procurement.

Selection Notes

Select this component when a stable 10V reference is required with strict accuracy and low noise specifications. The ±0.1% initial accuracy and 10ppm/°C temperature coefficient make it suitable for applications demanding high precision. Consider the 1.4mA supply current and 10mA output drive capability to ensure it meets the power budget and load requirements of the target circuit design.

Part Context

The REF102AUG4 belongs to the REF102 family of precision voltage references manufactured by Texas Instruments. This series is designed for applications requiring high stability and low noise. The 'G4' suffix typically denotes a specific revision or manufacturing origin within the product line, maintaining functional equivalence with other REF102 variants while potentially differing in packaging or environmental certifications.

Replacement Considerations

Public confirmed substitute part numbers include Analog Devices Inc. equivalents available in stock. Verify electrical parameter compatibility, specifically output voltage, tolerance, and package type, before substituting. Ensure the alternative device meets the same temperature range and noise specifications for seamless integration.
