TLE2425CLP

The TLE2425CLP by Texas Instruments is a precision virtual ground IC designed to simplify analog system design, particularly in applications using a single power source. It eliminates the need for multiple discrete components like resistors, capacitors, operational amplifiers, and voltage references by integrating a precision micropower voltage reference and a high-performance operational amplifier onto a single chip.

This device provides a stable 2.5-V virtual ground for 5-V/GND analog systems. Key electrical specifications include a typical output current capability of 50 mA (sink or source), a supply voltage range from 4 V to 40 V, and micropower operation with a typical quiescent current of 170 µA. It exhibits excellent regulation characteristics, with typical output regulation of -45 µV at 0 to -10 mA and +15 µV at 0 to +10 mA, and an input regulation of 1.5 µV/V. The low-impedance output is typically 0.0075 Ω.

The TLE2425CLP operates over a wide temperature range of -55°C to 125°C. It is available in multiple package options, including SOIC (8-pin), TO-92 (3-pin), and SOP (8-pin). Use of the TLE2425 can lead to increased dynamic signal range, improved signal-to-noise ratio, lower distortion, and easier interfacing to ADCs and DACs compared to traditional solutions.

This component is suitable for signal-conditioning applications where a precise reference voltage for signal grounds is required. Its integrated design simplifies board layout and reduces component count, making it an efficient choice for various analog circuits.
