REF102BP

Overview

The REF102BP 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 processing

Applications

• High-resolution data acquisition systems requiring precise reference voltages
• Precision instrumentation amplifiers and measurement circuits
• Analog-to-digital converter (ADC) reference inputs
• Calibration equipment and test instruments

Procurement Notes

Verify the specific suffix designation against official datasheets to confirm package type and temperature grade. Ensure compatibility with existing PCB footprints and thermal management requirements. Confirm RoHS compliance status for environmental regulations. Validate that the supplier source matches the manufacturer's authorized distribution channels to guarantee authenticity and traceability.

Selection Notes

Select this component when a stable 10V reference is required with minimal drift over temperature. Consider the ±0.1% initial accuracy for applications demanding high precision without external trimming. Evaluate the 1.4mA supply current against power budget constraints. Ensure the input voltage remains within the specified 11.4V to 36V range for proper regulation.

Part Context

The REF102 belongs to Texas Instruments' family of precision series voltage references, designed for applications requiring high stability and low noise. This specific model offers a fixed 10V output, distinguishing it from other variants in the series that provide different voltage levels or accuracies. It serves as a critical reference element in analog front-end designs where signal integrity depends on a highly stable voltage source.
