Overview
The TLE2142ACDR is a high-performance, internally compensated operational amplifier from Texas Instruments, part of the TLE214x and TLE214xA series. These devices are built using the Excalibur complementary bipolar process, offering low noise, high speed, and precision characteristics. The TLE2142ACDR is particularly noted for its low audio-band noise, high gain-bandwidth product, and fast settling time, making it suitable for a variety of high-fidelity and high-speed applications.
