Overview
The TLE2142CD is a high-performance, internally compensated operational amplifier produced by Texas Instruments. It is part of the TLE214x and TLE214xA series, built using the complementary bipolar Excalibur process. These devices are pin-compatible upgrades to standard industry products and are known for their low noise, high speed, and precision characteristics. The TLE2142CD is particularly suited for applications requiring fast settling times, low audio-band noise, and high gain-bandwidth product.
