REF3220AIDBVR

Overview

The REF3220AIDBVR is a fixed series voltage reference IC manufactured by Texas Instruments, housed in a SOT-23-6 surface-mount package. It provides a fixed output voltage of 2.048V with an initial accuracy tolerance of ±0.2%. The device operates within an input voltage range of 2.098V to 5.5V and draws a supply current of 135µA. It supports a maximum output current of 10mA and features a temperature coefficient of 20ppm/°C. Noise specifications include 27µVp-p from 0.1Hz to 10Hz and 39µVrms from 10Hz to 10kHz. The component is rated for operation between -40°C and 125°C.

Feature Summary

Delivers a precise fixed output voltage of 2.048V with high initial accuracy.
Features low noise performance suitable for sensitive analog signal chains.
Operates efficiently with a low supply current of 135µA.
Provides robust thermal stability across a wide industrial temperature range.

Applications

Precision data acquisition systems requiring stable reference voltages
Portable instrumentation powered by single-cell batteries
Industrial process control loops with strict accuracy requirements

Procurement Notes

Verify the specific suffix (DBVR) confirms the tape-and-reel packaging format required for automated assembly processes. Confirm that the NRND status does not impact long-term supply chain viability for existing production lines. Ensure compatibility with RoHS3 compliance standards if environmental regulations apply to the final product deployment.

Selection Notes

Select this component when a 2.048V reference is specifically required rather than standard 2.5V or 3.3V options. Consider the low quiescent current for battery-operated applications where power efficiency is critical. Evaluate the SOT-23-6 footprint against available PCB space constraints compared to larger packages.

Part Context

This part belongs to the REF32xx family of precision voltage references from Texas Instruments. It shares architectural similarities with other members like the REF3225 and REF3230 but differs in its fixed output voltage setting. The device is designed for applications demanding high accuracy and low drift in compact form factors.
