Overview
The TLE2142MD is a high-performance, internally compensated operational amplifier produced by Texas Instruments. It is part of the TLE214x series, built using the complementary bipolar Excalibur process. This device is a pin-compatible upgrade to standard industry operational amplifiers and is known for its low noise, high speed, and high drive capabilities. The TLE2142MD is available in an 8-pin SOIC (D) package and is characterized for operation over the full military temperature range of -55°C to 125°C.
