The incredible versatile op amp in medical apps

摘要

Operational amplifiers (op amps) are a staple in modern electronics. Found in everything from industrial flow metering to ultrasound imaging, versatility is their appeal. This building block is unique in that no other single integrated circuit (IC) can be used in so many different applications and configurations. Besides providing amplification, op amps can realize a wide range of functions such as summing, buffering, subtraction, integration, differentiation, filtering, inversion, and current to-voltage conversion, to name a few…
