TLE2426ILP

Overview

The TLE2426ILP is a precision virtual ground generator from Texas Instruments, designed to split a single power supply into dual polarized rails. It operates within an input voltage range of 4V to 40V and provides an adjustable output voltage between 2V and 20V. The device features an initial accuracy of 1% and a temperature coefficient of 35 ppm/°C. It supports a maximum shunt current of 20mA and draws a typical supply current of 400µA. The component is housed in an 8-pin PDIP package and functions as a series reference topology.

Feature Summary

• Generates a precise virtual ground by splitting a single-ended supply into positive and negative rails
• Provides high accuracy with 1% initial tolerance for stable reference applications
• Capable of sourcing and sinking up to 20mA to drive load currents effectively

Applications

• Audio amplifier circuits requiring dual power supplies from a single source
• Precision measurement systems needing stable mid-rail references
• Instrumentation interfaces utilizing split-rail operational amplifiers

Procurement Notes

Verify the specific suffix 'ILP' corresponds to the industrial temperature grade and PDIP-8 through-hole package configuration. Confirm that the ordering part number matches the required lead time and packaging format, as variations exist between tube and tape-and-reel options. Ensure compatibility with the target PCB footprint for the 8-pin DIP form factor before finalizing procurement orders.

Selection Notes

Select this component when a low-noise, high-current virtual ground is required for audio or precision analog applications. The 20mA output capability exceeds many standard rail splitters, allowing direct driving of op-amp inputs without additional buffering. Consider the 35 ppm/°C temperature coefficient for environments with significant thermal fluctuations compared to lower-drift alternatives.

Part Context

This device belongs to the TLE2426 family of rail splitter ICs manufactured by Texas Instruments. It serves as a dedicated solution for converting single-supply systems into dual-supply architectures. The ILP variant specifically denotes the industrial temperature range and plastic dual-in-line package, distinguishing it from commercial or surface-mount equivalents within the same functional series.
