This document is a presentation about operational amplifier (op-amp) applications by Mr. C.R. Shinde. It discusses several topics about op-amps including their introduction, symbol, operating modes, characteristics, and configurations. It also describes some specific op-amp applications like zero crossing detector, Schmitt trigger, and waveform generators. The overall purpose is to introduce the operational amplifier and some of its common uses in circuits.
