REF102CUG4

Overview

The REF102CUG4 is a precision 10V series voltage reference manufactured by Texas Instruments. It features laser-trimmed drift of 2.5ppm/°C maximum for the C-grade variant over the industrial temperature range. The device operates with an input voltage up to 40V and consumes low power, typically around 1mA. It is housed in an 8-pin SOIC package.

Feature Summary

• Provides a stable 10V fixed output via a series reference topology
• Laser-trimmed for high accuracy and low temperature coefficient
• Designed for low power consumption applications

Applications

• Precision data acquisition systems
• High-resolution analog-to-digital converter references
• Instrumentation amplifier references

Procurement Notes

Verify component status as this specific suffix may indicate end-of-life or obsolete status. Confirm availability of recommended manufacturer substitutes such as the REF102CU. Ensure compatibility with existing PCB footprints and validate that the C-grade specifications meet current design requirements before procurement.

Selection Notes

Select this component when a precise 10V reference is required with minimal thermal drift. The C-grade specification ensures performance within the industrial temperature range. Consider the 8-pin SOIC package constraints and verify input voltage headroom requirements against the 40V maximum limit.

Part Context

This part belongs to the REF102 family of precision voltage references from Texas Instruments. It serves as a high-accuracy reference source for analog circuits requiring stability over temperature variations. The C-grade designation specifies the thermal drift performance level.

Replacement Considerations

Texas Instruments recommends the REF102CU as a substitute. Verify pinout compatibility and electrical parameter alignment, particularly the 10V output and thermal drift characteristics, when transitioning to alternative stock.
