Overview
The TLC2272CP is a dual operational amplifier from Texas Instruments, part of the TLC227x family. These devices are known for their advanced LinCMOS technology, offering rail-to-rail output performance which enhances the dynamic range in both single-supply and split-supply applications. The TLC2272CP provides high gain-bandwidth (2.2 MHz typical) and a high slew rate (3.6 V/μs typical), making it suitable for higher-speed applications. It also features low noise (9 nV/√Hz typical at f = 1 kHz) and low input offset voltage (950 μV maximum at TA = 25°C), making it an excellent choice for precision and small-signal conditioning tasks.
