TLE2426ID

Overview

The TLE2426ID 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 40 V and provides an output accuracy of ±1%. The device features a temperature coefficient of 35 ppm/°C and supports a maximum shunt current of 20 mA. It is housed in an 8-SOIC surface-mount package and functions reliably across an extended industrial temperature range from -55°C to +125°C.

Feature Summary

• Generates a stable mid-supply reference voltage for single-supply systems
• Provides high output current capability for driving loads directly
• Maintains low output impedance for improved load regulation

Applications

• Creating dual-polarity supplies for operational amplifiers
• Establishing reference points for analog-to-digital converters
• Biasing circuits in audio signal processing equipment

Procurement Notes

Verify the specific suffix ID against the official datasheet to confirm the SOIC-8 package and industrial temperature grade. Ensure compatibility with existing PCB footprints and thermal management requirements before finalizing procurement decisions.

Selection Notes

Select this component when a precise virtual ground is required for single-supply applications. Consider the 20 mA output current limit and the 40 V maximum input voltage when designing the power stage. Verify that the operating environment falls within the specified -55°C to +125°C range.

Part Context

This part belongs to the TLE2426 series of rail splitter devices. It serves as a dedicated solution for generating virtual grounds, replacing traditional resistor divider networks that suffer from high output impedance and poor load regulation characteristics.

Replacement Considerations

TLE2426IDR is a tape-and-reel variant of the same functional device. TLE2426CD offers a commercial temperature range alternative.
