REF5020ID

Overview

The REF5020ID is a precision series voltage reference IC manufactured by Texas Instruments, housed in an 8-SOIC surface-mount package. It provides a fixed output voltage of 2.048 V with an initial accuracy of ±0.05%. The device operates within an input voltage range of 2.7 V to 18 V and draws a supply current of 800 µA to 1.2 mA. It features a low temperature coefficient of 3 ppm/°C and exhibits low noise characteristics, specified at 6 µVpp/V from 0.1 Hz to 10 Hz. The unit supports a maximum shunt current of 10 mA and functions reliably across an extended temperature range of -40°C to +125°C.

Feature Summary

• Delivers high-precision voltage regulation with tight initial tolerance and minimal drift over temperature variations.
• Incorporates low-noise architecture suitable for sensitive analog signal processing applications.
• Offers robust operational stability across a wide input voltage span and extreme environmental temperatures.

Applications

• High-resolution data acquisition systems requiring stable reference voltages
• Precision instrumentation amplifiers and sensor interfaces

Procurement Notes

Verify the specific suffix against official datasheets to confirm package type and temperature grade. Ensure compatibility with existing PCB footprints for SOIC-8 components. Confirm moisture sensitivity levels and storage requirements prior to assembly. Cross-reference manufacturer part numbers with distributor listings to validate authenticity and revision history.

Selection Notes

Select this component when fixed 2.048 V output is required with stringent accuracy constraints. Consider the low power consumption and small form factor for space-constrained designs. Evaluate thermal management needs given the operating temperature range and self-heating effects under load conditions.
