REF5010AIDR

Overview

The REF5010AIDR 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 10.2V to 18V and draws a supply current of 1.2mA. It features a low noise performance of 30µVpp from 0.1Hz to 10Hz and a temperature coefficient of 8ppm/°C. The component supports a maximum output current of 10mA and functions reliably across a wide operating temperature range from -40°C to +125°C. It is housed in an 8-SOIC surface-mount package.

Feature Summary

• Delivers high-precision fixed voltage output with tight initial accuracy tolerance
• Maintains stability over wide temperature variations with low drift characteristics
• Provides low-noise performance suitable for sensitive analog signal processing

Applications

• High-resolution data acquisition systems requiring stable reference voltages
• Precision instrumentation and measurement equipment
• Industrial process control applications demanding long-term stability

Procurement Notes

Verify the specific suffix 'DR' indicates tape-and-reel packaging when sourcing components. Confirm that the ±0.1% accuracy class matches the design requirements, as other variants may offer different tolerances. Ensure the 8-SOIC package footprint aligns with the printed circuit board layout. Check for RoHS compliance status if environmental regulations apply to the manufacturing process.

Selection Notes

Select this component when a fixed 10V reference is required with high accuracy and low noise. Consider the 1.2mA supply current against power budget constraints. Evaluate the 8-SOIC package size relative to available board space. Compare the 8ppm/°C temperature coefficient against application thermal stability needs. Verify input voltage headroom requirements fall within the specified 10.2V to 18V range.

Part Context

This part belongs to the REF50xx family of precision voltage references from Texas Instruments. The family includes various output voltages and packages, such as the REF5010IDGKR in VSSOP format. The REF5010AIDR specifically utilizes the SOIC-8 package and offers ±0.1% accuracy, distinguishing it from higher or lower precision variants within the same product line.

Replacement Considerations

The REF5010AID is a tube-packaged version of the same electrical specification. The REF5010AIDR is functionally identical but differs only in packaging format. No direct cross-manufacturer substitutes are confirmed in the provided documentation.
