REF3240AIDBVTG4

Overview

The REF3240AIDBVTG4 is a precision series voltage reference from Texas Instruments, delivering a fixed output of 4.096 V. It features an initial accuracy of ±0.2% and a temperature coefficient of 20 ppm/°C. The device operates within an input voltage range of 4.146 V to 5.5 V and draws a supply current of 135 µA. It supports a maximum load current of 10 mA and functions reliably across a temperature range of -40°C to +125°C. Packaged in a compact SOT-23-6 surface-mount case, it offers low noise performance with 53 µVp-p (0.1Hz to 10Hz) and 78 µVrms (10Hz to 10kHz).

Feature Summary

• Provides stable 4.096 V reference with high initial accuracy.
• Low power consumption suitable for battery-operated systems.
• Compact SOT-23-6 package for space-constrained designs.

Applications

• Portable instrumentation requiring precise voltage references.
• Battery-powered measurement devices.
• Data acquisition systems needing stable analog references.

Procurement Notes

Verify the exact suffix G4 against the manufacturer's latest documentation to ensure compliance with current RoHS standards and material declarations. Confirm that the SOT-23-6 package marking aligns with your assembly requirements. Check for any specific handling instructions related to moisture sensitivity level 2. Ensure the component status is reviewed as some variants may be marked as not recommended for new designs.

Selection Notes

Select this component when a fixed 4.096 V output is required with tight tolerance specifications. The low quiescent current makes it ideal for energy-efficient applications. Consider the SOT-23-6 footprint compatibility during PCB layout. Evaluate the thermal performance within the specified operating temperature range to ensure long-term stability in harsh environments.

Part Context

This part belongs to the REF3240 family of precision voltage references manufactured by Texas Instruments. It is designed for applications demanding high accuracy and low power consumption.
