TLE2425IDR

The TLE2425IDR from Texas Instruments is a 3-terminal precision virtual ground device, simplifying designs that require a reference voltage for signal grounds in single-power-source applications. It integrates a precision micropower voltage reference and a high-performance operational amplifier on a single chip, eliminating the need for multiple discrete components.

This device is suitable for 5-V/GND analog systems and provides a 2.5-V virtual ground. Key electrical characteristics include a typical output current capability of 20 mA, micropower operation with a typical quiescent current of 170 µA, and excellent regulation. The output regulation is typically -45 µV at IO = 0 to -10 mA and +15 µV at IO = 0 to +10 mA. Input regulation is typically 1.5 µV/V, and the output impedance is a low 0.0075 Ω.

The TLE2425IDR operates over a wide temperature range of -55°C to 125°C and supports supply voltages from 4 V to 40 V. It is available in SOIC, TO-92, and SOP packages, with surface mount as the typical mounting type.

Using the TLE2425IDR enhances dynamic signal range, improves signal-to-noise ratio, reduces distortion, and increases signal accuracy compared to traditional solutions. It also facilitates easier interfacing with ADCs and DACs.
