Overview
The TLE2426CLPE3 is a precision virtual ground reference IC from Texas Instruments, designed to split a single power supply into positive and negative rails. It operates within an input voltage range of 2 V to 20 V and delivers an output accuracy of 1%. The device features a temperature coefficient of 35 PPM/°C and supports a maximum series input voltage of 40 V with a shunt current capacity of 20 mA. It functions reliably across an extended temperature range from -55°C to +125°C and is housed in a TO-92-3 through-hole package.
Feature Summary
- Generates a stable mid-supply reference point for dual-rail operation using a single power source
- Provides high initial accuracy for precise signal conditioning applications
- Capable of sourcing and sinking load current to maintain virtual ground stability
Applications
- Dual-supply operational amplifier biasing
- Audio circuit power distribution
- Data acquisition system reference generation
Procurement Notes
Verify the specific suffix 'E3' indicates lead-free composition and RoHS compliance as per manufacturer specifications. Confirm the TO-92-3 through-hole package matches your PCB footprint requirements. Ensure the operating environment stays within the specified -55°C to +125°C range to maintain the stated 1% accuracy and 35 PPM/°C temperature coefficient performance.
Selection Notes
Select this component when a low-cost, through-hole solution is required for splitting single supplies in industrial or automotive environments. The wide operating temperature range makes it suitable for harsh conditions where standard commercial grade parts may fail. Consider the 20 mA output current limit when designing load circuits to ensure the virtual ground remains stable under varying load conditions.
Part Context
This part belongs to the TLE2426 family of rail splitter devices. It serves as a fundamental building block for creating bipolar power supplies from unipolar sources. The CLPE3 designation specifies the commercial temperature variant with enhanced environmental compliance, distinguishing it from automotive qualified or industrial temperature extended variants within the same functional family.
Replacement Considerations
TLE2426CLP is the non-E3 equivalent without explicit lead-free declaration. TLE2426IDG4 offers SOIC surface mount packaging with improved 25 PPM/°C temperature coefficient. TLE2426QDRG4Q1 provides AEC-Q100 automotive qualification in an 8-SOIC package.
