REF3320AIDBZT

Overview

The REF3320AIDBZT is a precision series voltage reference from Texas Instruments, delivering a fixed output of 2.048 V with an initial accuracy of 0.15%. It features a low temperature coefficient of 30 ppm/°C and operates within a supply voltage range up to 5.5 V. The device draws a typical quiescent current of 3.9 μA, making it suitable for battery-powered applications. It supports a maximum shunt current of 5 mA and functions reliably across an extended industrial temperature range from -40°C to +125°C. Packaged in a compact SOT-23-3 footprint, it integrates high stability and low power consumption.

Feature Summary

• Provides stable 2.048 V output with 0.15% initial accuracy
• Low temperature drift of 30 ppm/°C ensures precision over temperature
• Ultra-low quiescent current of 3.9 μA optimizes power efficiency
• Extended operational reliability across -40°C to +125°C

Applications

• Portable instrumentation requiring precise voltage standards
• Battery-operated data acquisition systems
• Calibration equipment needing stable reference sources
• Industrial process control signal conditioning

Procurement Notes

Verify the specific suffix 'DBZT' corresponds to the tape-and-reel packaging format rather than tube or cut tape variants. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Ensure the ordering part number matches the exact package type and temperature grade specified in your design documentation to avoid integration errors.

Selection Notes

Select this component when a 2.048 V reference is required with strict low-power constraints. The SOT-23-3 package offers space efficiency for dense PCB layouts. Consider the 30 ppm/°C drift specification against your system's thermal environment. Evaluate the 5.5 V maximum input voltage against your available supply rails to ensure adequate headroom for proper regulation.

Part Context
