TLE2426MD

Overview

The TLE2426MD is a precision ground reference voltage IC manufactured by Texas Instruments, housed in an 8-SOIC surface-mount package. It functions as a rail splitter to create a virtual ground from a single power supply. The device provides an adjustable output voltage ranging from 2 V to 20 V with an initial accuracy of ±1%. It supports a maximum input voltage of 40 V and delivers a maximum shunt current of 20 mA. The component operates within a temperature range of -55°C to +125°C and features a standard temperature coefficient of 35 ppm/°C.

Feature Summary

• Generates a stable virtual ground midpoint from a single-ended power supply
• Provides high-precision voltage referencing with low drift characteristics
• Capable of sourcing and sinking significant load currents for active circuits

Applications

• Splitting single-supply rails for dual-polarity analog circuit operation
• Providing precise reference voltages for data acquisition systems
• Biasing operational amplifiers in audio and sensor signal conditioning

Procurement Notes

Verify the specific suffix against the manufacturer datasheet to confirm package type and temperature grade. Ensure the ordering code matches the required SOIC-8 variant. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process before finalizing procurement.

Selection Notes

Select this component when a reliable mid-rail reference is needed for single-supply applications. The wide operating temperature range suits industrial environments. Consider the 20 mA output capability for driving moderate loads directly without additional buffering stages.

Part Context

This part belongs to the TLE2426 series of precision ground references. It is designed to replace traditional resistor divider networks that suffer from poor regulation and high output impedance. The series offers improved stability and current drive capabilities compared to passive solutions.

Replacement Considerations

TLE2426CP and TLE2426IP are pin-compatible alternatives offering identical functionality in PDIP packages.
