TLE2426IDRG4

Overview

The TLE2426IDRG4 is a precision virtual ground reference IC manufactured by Texas Instruments, designed to split a single power supply rail into positive and negative rails. It operates within an input voltage range of 4 V to 40 V and provides an adjustable output voltage from 2 V to 20 V with an initial accuracy of ±1%. The device features a low quiescent current of 400 µA maximum and supports a maximum output current of 20 mA. It utilizes an 8-SOIC surface-mount package and ensures stable performance across a wide operating temperature range of -40°C to +85°C.

Feature Summary

• Generates a precise virtual ground to create dual polarity supplies from a single source
• Provides high accuracy voltage regulation with ±1% initial tolerance
• Supports wide input voltage ranges up to 40 V for flexible system integration

Applications

• Single-supply operational amplifier circuits requiring bipolar power rails
• Audio signal processing systems needing clean virtual ground references
• Data acquisition interfaces isolating analog and digital ground potentials

Procurement Notes

Verify the specific suffix 'G4' indicates RoHS compliance and lead-free manufacturing status as per Texas Instruments standards. Confirm the SOIC-8 package dimensions match your PCB footprint requirements. Ensure the selected distributor sources genuine components to avoid counterfeit risks associated with legacy or discontinued series parts.

Selection Notes

Select this component when a stable mid-rail reference is required for single-supply analog designs. It is suitable for applications demanding low noise and high accuracy without complex external circuitry. Consider the thermal management capabilities of the SOIC-8 package if operating near maximum current limits in enclosed environments.

Part Context

This part belongs to the TLE2426 family of 'Rail Splitter' devices, widely used for converting unipolar power sources into bipolar supplies. The IDRG4 variant specifically denotes the industrial temperature grade version housed in a reel-packaged SOIC-8 format, optimized for automated surface-mount assembly processes.

Replacement Considerations

Direct pin-compatible alternatives include the TLE2426IDR and TLE2426IDG4. Verify that substitute parts maintain identical voltage ratings, current capabilities, and package specifications to ensure seamless integration without redesigning the host circuit board.
