TLE2426IDG4

Overview

The TLE2426IDG4 is a precision virtual ground generator 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 2 V to 20 V, with a maximum series input voltage of 40 V. The device provides an initial accuracy of 1% and features a temperature coefficient of 25 ppm/°C. It delivers a maximum shunt current of 31 mA while consuming a typical operating supply current of 280 µA. The component is housed in an SOIC-8 surface-mount package and supports an extended industrial temperature range from -55°C to +125°C.

Feature Summary

• Generates a stable mid-supply reference voltage for single-supply systems
• Maintains output voltage at exactly half the input potential
• Provides low output impedance for improved load regulation
• Operates efficiently with minimal quiescent current consumption

Applications

• Creating dual-polarity supplies for operational amplifiers
• Establishing reference points for analog-to-digital converters
• Biasing circuits in battery-powered instrumentation
• Providing virtual grounds for audio signal processing

Procurement Notes

Verify the specific suffix 'DG4' indicates lead-free compliance and RoHS status as per Texas Instruments documentation. Confirm the SOIC-8 package dimensions match your PCB footprint requirements. Ensure the thermal rating aligns with your system's ambient temperature constraints. Check for any recent product discontinuance notifications or alternative recommendations from the manufacturer before finalizing procurement plans.

Selection Notes

Select this component when a precise, low-noise virtual ground is required for high-accuracy analog applications. The wide temperature range makes it suitable for industrial environments. Consider the 31 mA output current capability against your load requirements. The SOIC-8 package offers a compact solution for space-constrained designs compared to through-hole alternatives.

Part Context

This device belongs to the TLE2426 family of precision virtual ground generators. It serves as a critical interface between single-ended power sources and dual-rail analog circuitry. The component simplifies design by eliminating the need for complex resistor dividers or additional op-amp configurations to achieve a stable mid-point reference.
