The Use of Operational Amplifier in Providing Safety for Electronic Devices

Oluyamo Sunday Samuel, Olusola O. Ibukun

Abstract


Operational amplifiers find a wide application and usage in electronics, control and instrumentation circuits. This paper discusses the use of operational amplifier commonly referred to as Op-Amp in ensuring the longevity of electronic systems. Devices such as automatic voltage regulators, automatic inverter systems and so on make use of OP-Amp to provide safety for the system and other components that make up the device. In this work, the Op-Amp is used to provide overload and no load indication. A low and high battery level indication when in use and while undergoing charging process is ensured respectively; this however elongates the life-span of the battery. With the aid of an external shutdown circuit arrangement, the entire system can be shut down after given a prior warning alarm.

Keywords: Op-Amp, battery, Electronic Devices, Inverter.
