REF5010IDR

Overview

The REF5010IDR is a precision series voltage reference integrated circuit manufactured by Texas Instruments. It provides a fixed output voltage of 10V with an initial accuracy of ±0.05%. The device operates within an input voltage range of 5.2V to 18V and draws a supply current of 800µA. It features a low temperature coefficient of 3ppm/°C and supports a maximum load current of 10mA. The component is housed in an 8-SOIC surface-mount package and functions reliably across a junction temperature range of -40°C to +125°C.

Feature Summary

• Delivers high-precision fixed voltage output with tight initial accuracy tolerance
• Maintains stable performance through very low temperature coefficient characteristics
• Operates efficiently with low quiescent supply current consumption

Applications

• High-resolution data acquisition systems requiring precise reference voltages
• Industrial process control instrumentation calibration circuits
• Medical equipment signal conditioning stages

Procurement Notes

Verify the specific suffix 'IDR' corresponds to the 8-SOIC package and tape-and-reel delivery format. Confirm that the initial accuracy grade matches the required ±0.05% specification for the target application. Ensure compatibility with the 10V output requirement and check for any recent product change notices regarding manufacturing site or material composition updates.

Selection Notes

Select this component when a stable 10V reference is needed with minimal drift over temperature variations. Consider the 800µA supply current for power-sensitive designs. Verify that the SOIC-8 footprint fits the PCB layout constraints. Compare noise specifications against other REF50xx variants if ultra-low noise is critical for the analog front end.

Part Context

This part belongs to the REF50xx family of low-noise, very low drift precision voltage references from Texas Instruments. The family includes various output voltages such as 2.5V, 5V, and 10V. The REF5010 variant specifically targets applications demanding high accuracy and stability in compact surface-mount packages.

Replacement Considerations

Direct pin-compatible substitutes within the same family include REF5010IDRG4. Other manufacturers may offer equivalent 10V references, but verify parameter alignment for accuracy, temperature coefficient, and package dimensions before substitution.
