REF102CP

Overview

The REF102CP is a precision series voltage reference integrated circuit manufactured by Texas Instruments. It provides a fixed output voltage of 10V with an initial accuracy 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 features a temperature coefficient of 10ppm/°C and low noise performance of 5µVp-p from 0.1Hz to 10Hz. The component supports a maximum output current of 10mA and functions reliably across a temperature range of -25°C to 85°C in an 8-SOIC package.

Feature Summary

• Delivers high-precision fixed voltage output with tight initial accuracy tolerance
• Maintains stable reference levels over wide operating temperature ranges
• Provides low-noise performance suitable for sensitive analog signal chains

Applications

• High-resolution data acquisition systems requiring stable reference voltages
• Precision instrumentation amplifiers and sensor interfaces
• Analog-to-digital converter (ADC) reference inputs
• Calibration equipment and test measurement devices

Procurement Notes

Verify the specific suffix designation against the manufacturer's official datasheet to confirm pinout compatibility and thermal characteristics. Ensure the selected variant matches the required operating temperature range and packaging style for your PCB layout. Cross-reference the part number with authorized distributors to confirm current availability and authenticity before procurement.

Selection Notes

Select this component when a stable 10V reference is required with minimal drift over temperature. Consider the input voltage headroom needed, as the minimum operating voltage is 11.4V. Evaluate the power dissipation based on the supply voltage and load current to ensure adequate thermal management within the SOIC package constraints.

Part Context

The REF102 belongs to Texas Instruments' family of precision series voltage references, designed for applications demanding high stability and low noise. This specific model offers a 10V output, complementing other variants in the series that provide different voltage levels. The device utilizes bandgap technology to achieve its specified accuracy and temperature performance characteristics.

Replacement Considerations

Check for direct pin-compatible alternatives such as the REF102AU or REF102BU if the CP suffix is unavailable. Verify that substitute parts maintain the same 10V output, ±0.1% accuracy, and 8-SOIC package dimensions to ensure seamless integration without redesigning the PCB footprint.
