TLE2426QDRG4Q1

Overview

The TLE2426QDRG4Q1 is an automotive-grade precision virtual ground voltage reference IC manufactured by Texas Instruments. It operates within a supply voltage range of 4V to 40V and provides an adjustable output voltage between 2V and 20V with a tolerance of ±1%. The device draws a typical supply current of 400µA and supports a maximum output current of 20mA. It features a temperature coefficient of 35ppm/°C and low noise of 120µVrms from 10Hz to 10kHz. Qualified under AEC-Q100 standards, it functions reliably across a temperature range of -40°C to +125°C in an 8-SOIC surface-mount package.

Feature Summary

• Provides a stable virtual ground reference for dual-supply systems using a single power source
• Automotive qualification ensures reliability and performance consistency under harsh operating conditions
• Low quiescent current consumption supports energy-efficient circuit designs
• Adjustable output voltage allows flexibility in setting precise mid-rail reference points

Applications

• Dual-supply operational amplifier biasing in automotive audio and sensor interfaces
• Precision analog signal conditioning circuits requiring a stable virtual ground
• Data acquisition systems needing accurate mid-supply reference voltages
• Battery-powered automotive electronics requiring efficient single-supply operation

Procurement Notes

Verify the complete part number including suffixes such as G4 and Q1 to ensure correct packaging, temperature grade, and automotive qualification status. Confirm that the specific revision matches the design requirements for AEC-Q100 compliance. Check official Texas Instruments documentation for any recent product change notices or lifecycle updates before finalizing procurement decisions.

Selection Notes

Select this component when a high-precision virtual ground is required for automotive applications. Ensure the input voltage stays within the 4V to 40V range and the load current does not exceed 20mA. Consider the 8-SOIC package dimensions for PCB layout constraints. Verify thermal management needs given the 125°C maximum junction temperature rating.

Part Context

This device belongs to the TLE2426 family of rail splitter integrated circuits. The Q1 suffix denotes automotive qualification, while G4 indicates lead-free and RoHS-compliant manufacturing. It serves as a dedicated solution for creating virtual grounds in single-supply systems that interface with dual-supply analog components.

Replacement Considerations

TLE2426CDR is a non-automotive commercial grade alternative with similar electrical characteristics but different temperature and qualification specifications.
