TLE2426CD

Overview

The TLE2426CD is a precision virtual ground generator manufactured by Texas Instruments, designed to split a single power supply into dual rails. It operates within an input voltage range of 2 V to 20 V and delivers an initial accuracy of 1%. The device features a temperature coefficient of 35 ppm/°C and supports a maximum series input voltage of 40 V. It provides a maximum shunt current of 20 mA and functions reliably across a temperature range from -55°C to +125°C. Packaged in an SOIC-8 surface-mount format, it serves as a stable reference for analog circuits requiring symmetrical supplies.

Feature Summary

• Generates a precise mid-supply reference voltage effectively splitting a single rail into dual polarities
• Maintains high output stability with low temperature drift characteristics over wide operating ranges
• Provides sufficient drive capability for moderate load currents without external buffering components

Applications

• Single-supply operational amplifier biasing
• Audio circuit virtual ground generation
• Analog-to-digital converter reference creation
• Sensor interface signal conditioning

Procurement Notes

Verify the specific suffix 'CD' corresponds to the commercial temperature grade (-55°C to +125°C) and SOIC-8 package variant. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure design margins account for the specified 20 mA maximum shunt current limit under all expected load conditions.

Selection Notes

Select this component when a compact surface-mount solution is required for creating a stable virtual ground in single-supply systems. It is suitable for applications demanding 1% initial accuracy and operation up to 40 V input. Consider thermal management if operating near the upper temperature limits or maximum current specifications.

Part Context

Part of the TLE2426 family of rail splitter ICs, offering a dedicated solution for converting unipolar power sources into bipolar references. This specific CD variant utilizes an SOIC-8 package, distinguishing it from through-hole alternatives like the DIP or TO-92 versions within the same product line.
