REF5010IDGKR

Overview

The REF5010IDGKR is a precision series voltage reference manufactured by Texas Instruments, housed in an 8-VSSOP package. It provides a fixed output voltage of 10V with an initial accuracy tolerance of ±0.05%. The device operates within an input voltage range of 10.2V to 18V and draws a supply current of 1.2mA. Key performance metrics include a temperature coefficient of 3ppm/°C and low noise characteristics of 30µVpp from 0.1Hz to 10Hz. It supports a maximum output current of 10mA and functions reliably across an extended temperature range of -40°C to +125°C.

Feature Summary

• Delivers high-precision fixed voltage output with tight initial accuracy tolerance
• Exhibits very low drift characteristics suitable for sensitive measurement applications
• Features low noise performance to minimize signal interference in analog circuits

Applications

• High-resolution data acquisition systems requiring stable reference voltages
• Precision instrumentation and sensor signal conditioning circuits
• Medical equipment and industrial process control systems

Procurement Notes

Verify the specific suffix 'DGKR' corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the 8-VSSOP footprint matches the target PCB design constraints. Ensure the component meets RoHS3 compliance standards if mandated by the end-product regulations. Cross-reference the manufacturer part number against official distributor catalogs to validate authenticity and traceability before procurement.

Selection Notes

Select this component when a stable 10V reference is needed with minimal temperature drift. The 1.2mA supply current offers a balance between precision and power consumption. Consider the 10mA output drive capability for direct interfacing with ADCs or op-amps without additional buffering. The wide input voltage range allows flexibility in power supply design relative to the fixed output level.

Part Context

This part belongs to the REF50xx family of precision voltage references from Texas Instruments. The family is characterized by low noise and very low drift specifications. The REF5010 variant specifically targets applications requiring a 10V output. Other variants in the series offer different voltage levels such as 2.5V, 5V, and 3V, sharing similar architectural benefits and package options.

Replacement Considerations

Direct substitutes within the same family include REF5010IDGKT (tray packaging) and REF5010ID (SOIC-8 package). Verify pin compatibility and thermal performance when switching packages. Alternative manufacturers may offer comparable specs but require rigorous validation of noise and drift parameters.
