Overview
The TLC2272AM-MIL, specifically the TLC2272AMFKB, is a dual operational amplifier from Texas Instruments. This device is part of the TLC227x family, known for its advanced LinCMOS technology, which provides rail-to-rail output performance. This feature enhances the dynamic range in both single-supply and split-supply applications. The TLC2272AM-MIL offers a high gain-bandwidth product of 2.2 MHz and a slew rate of 3.6 V/μs, making it suitable for higher-speed applications. It is characterized by low noise, low input offset voltage, and low power dissipation, making it an excellent choice for small-signal conditioning and battery-powered applications.
