Overview
The TLE2426ILP, produced by Texas Instruments, is a precision virtual ground generator designed for signal-conditioning applications. It combines a high-performance, micropower operational amplifier and a precision-trimmed divider on a single silicon chip, ensuring an output voltage that is always half of the input voltage. This rail splitter is ideal for applications requiring a stable reference voltage, such as data acquisition front ends, analog signal termination, and precision voltage references. The device is available in a space-saving 3-terminal TO-92 package and offers optional 8-pin packages for enhanced noise reduction.
