TLE2426CD

The TLE2426CD from Texas Instruments is a precision virtual ground device designed for analog systems requiring a stable reference voltage at half the supply voltage. This 'rail splitter' IC simplifies designs by eliminating the need for multiple discrete components like resistors, capacitors, and operational amplifiers typically used to create a virtual ground.

Key electrical specifications include a wide supply voltage range from 4V to 40V, with a typical quiescent current of only 170 uA at 5V supply. It offers a high output current capability, sourcing and sinking up to 20 mA, with excellent output regulation of -45 uV and +15 uV respectively. The output impedance is a low 0.0075 Ω typical.

This device is suitable for signal-conditioning applications and operates across a wide temperature range of -55°C to 125°C. It is available in SOIC, TO-92, and PDIP packages, offering flexibility for various board space requirements. The TLE2426CD provides a precise V_O/V_I ratio of 0.5, making it an efficient solution for creating a reliable analog ground reference.

Designed for ease of use and space saving, the TLE2426CD integrates a high-performance, micropower operational amplifier and a precision-trimmed divider on a single chip. This integration results in a cost-effective and high-performance solution for creating a virtual ground in single-supply systems.
