REF3225AMDBVREPG4

Overview

The REF3225AMDBVREPG4 is a series voltage reference integrated circuit manufactured by Texas Instruments. It provides a fixed output voltage of 2.5 V with an initial accuracy tolerance of ±0.2%. The device operates within an input voltage range of 2.55 V to 5.5 V and supports a maximum load current of 10 mA. Key electrical specifications include a temperature coefficient of 40 ppm/°C, a supply current of 120 µA, and noise levels of 33 µVp-p (0.1 Hz to 10 Hz) and 48 µVrms (10 Hz to 10 kHz). It functions reliably across a junction temperature range of -55°C to 125°C and is housed in an SOT-23-6 surface-mount package.

Feature Summary

• Delivers a stable 2.5 V fixed output voltage suitable for precision analog circuits.
• Features low power consumption with a supply current of 120 µA for battery-operated applications.
• Provides high initial accuracy with a ±0.2% tolerance for precise measurement systems.
• Operates over an extended industrial temperature range from -55°C to 125°C.

Applications

• Portable instrumentation requiring low power and high accuracy.
• Battery-powered measurement devices needing stable reference voltages.
• Data acquisition systems utilizing analog-to-digital converters.
• Industrial process control loops requiring precise signal conditioning.

Procurement Notes

Verify the component status as obsolete or not recommended for new designs before procurement. Confirm that the specific suffix 'EP' indicates enhanced product specifications if required for your application. Ensure compatibility with the SOT-23-6 footprint during PCB layout. Check for moisture sensitivity level 2 requirements regarding storage and handling conditions prior to assembly.

Selection Notes

Select this component when a fixed 2.5 V reference with ±0.2% accuracy is required in a compact SOT-23-6 package. Consider the 40 ppm/°C temperature coefficient against stricter drift requirements. Evaluate the 120 µA supply current against total system power budgets. Verify that the 10 mA output current capability meets the load demands of the connected circuitry.

Part Context

This part belongs to the Texas Instruments REF32xx series of micropower voltage references. It shares the same core architecture and pinout as other variants in the family but is distinguished by its specific military-grade or enhanced product suffix. The series is designed for applications demanding low power consumption and small form factors without compromising on accuracy or stability.
