Overview
The TLE2426IP 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, delivering an output accuracy of 1% with a temperature coefficient of 35 ppm/°C. The device supports a maximum shunt current of 20 mA and functions reliably across an extended temperature range from -55°C to +125°C. Packaged in an 8-pin PDIP format, it provides a stable mid-rail reference for analog circuits.
Feature Summary
- Generates a precise virtual ground by splitting the input supply voltage
- Maintains high output accuracy with low temperature drift characteristics
- Provides sufficient drive current for moderate load requirements
Applications
- Single-supply operational amplifier biasing
- Audio signal processing circuit reference generation
- Analog sensor interface power management
Procurement Notes
Verify the specific suffix 'IP' corresponds to the through-hole PDIP-8 package variant when sourcing. Confirm that the required operating temperature range aligns with the industrial grade specifications documented for this part number. Ensure compatibility with existing PCB footprints before finalizing procurement decisions.
Selection Notes
Select this component when a robust through-hole solution is required for virtual ground applications. Consider the 20 mA current limit against expected load demands. Evaluate the 35 ppm/°C temperature coefficient against system stability requirements over the full operating temperature range.
Part Context
This device belongs to the TLE2426 series of rail splitter integrated circuits. It serves as a direct replacement for discrete resistor divider networks, offering superior load regulation and lower output impedance. The series is widely utilized in mixed-signal systems requiring clean mid-rail references.
Replacement Considerations
Compatible substitutes include the TLE2426ID (SOIC-8) and TLE2426ILPR (TO-92-3). Verify package footprint differences and thermal performance characteristics when transitioning between surface-mount and through-hole variants.
