TLE2426CP

Overview

The TLE2426CP is a precision rail-to-rail virtual ground circuit designed to split a single power supply into two equal, opposite polarity supplies. It functions as a dual output voltage regulator with low output impedance and high current capability. The device provides a stable reference point for analog circuits requiring bipolar operation from a unipolar source. Key electrical characteristics include a typical output impedance of less than 1 ohm and a short-circuit protection feature. It operates over an extended temperature range and maintains performance under varying load conditions.

Feature Summary

• Provides a precise virtual ground midpoint from a single supply
• Features internal short-circuit protection for robust operation
• Delivers low output impedance for stable voltage regulation

Applications

• Audio amplifier biasing circuits
• Operational amplifier power supply splitting
• Data acquisition systems requiring bipolar rails

Procurement Notes

Verify the package type matches the required footprint, specifically the 8-pin DIP or SOIC variant. Confirm the suffix indicates the correct temperature grade and packaging format. Ensure the ordering part number aligns with the specific pin configuration needed for the design. Cross-reference the manufacturer's latest datasheet for any updates on mechanical dimensions or electrical specifications before finalizing procurement.

Selection Notes

Select this component when a stable mid-supply reference is needed for single-supply systems. Consider the maximum output current requirements of the downstream circuitry. Evaluate the thermal dissipation capabilities if significant load currents are expected. Ensure the input voltage range falls within the specified limits for reliable virtual ground generation.

Part Context

This device belongs to Texas Instruments' family of precision voltage regulators and reference circuits. It is commonly used in conjunction with operational amplifiers and other analog signal processing components. The TLE2426 series offers a compact solution for creating bipolar power supplies without the need for complex transformer configurations or additional active components.

Replacement Considerations

Check for direct pin-compatible alternatives such as the TLV7033 if lower noise is required. Verify that substitute parts maintain similar output impedance and current drive capabilities. Ensure replacement components support the same operating voltage range and temperature specifications.
