TLE2425CD

The TLE2425CD from Texas Instruments is a 3-terminal precision virtual ground device. It is designed to provide a stable 2.5-V virtual ground for 5-V/GND analog systems, eliminating the need for multiple discrete components like resistors, capacitors, operational amplifiers, and voltage references.

This device features a high output current capability, capable of sinking or sourcing up to 20 mA typically. It operates with a supply voltage ranging from 4 V to 40 V and maintains excellent regulation characteristics. The typical output regulation is -45 uV at I O = 0 to -10 mA and +15 uV at I O = 0 to +10 mA, with an input regulation of 1.5 uV/V typically. Its low-impedance output is typically 0.0075 Ohm.

The TLE2425CD operates within a temperature range of -55°C to 125°C. It is available in multiple package options including SOIC (D), TO-92 (LP), and SOP (PS). The micropower operation consumes only 170 uA typically.

By integrating a precision micropower voltage reference and a high-performance precision operational amplifier, the TLE2425CD enhances dynamic signal range, improves signal-to-noise ratio, reduces distortion, and offers better signal accuracy compared to traditional solutions. This makes it suitable for various signal-conditioning applications.
