KA358S

KA358S is a general-purpose operational amplifier with many uses in a variety of applications. It is characterized by low cost and low-noise operation. Applications include audio amplification, instrumentation amplifiers, signal buffering, and wideband amplitude detection.The KA358S is designed to provide low-noise operation over a wide range of gain and frequency. It features a high slew rate, low input bias current, low supply current, and wideband frequency response from dc to greater than 100kHz. It is a single supply device operating from 4.5- to 15V.The KA358S can be used as a non-inverting amplifier for improving signal-to-noise ratio, common base amplifier for boosting output level, and as a summing amplifier for combining signals. It is also useful for applications wherein a low level signal needs to be amplified before being further processed or digitized.The output of the KA358S is short-circuit protected. In addition, it features a symmetry offset voltage that is adjustable to produce a rejection ratio of up to 70dB at unity gain.The KA358S works on the principle of feedback. A feedback loop is a system wherein the output of a process is used as an input to influence or modify the same process. In the KA358S, a feedback loop is incorporated that is composed of the amplifier, feedback resistor and feedback capacitor. This feedback loop is able to control the characteristics of the amplifier’s gain and frequency response.The output of the KA358S can be adjusted using the internal three-terminal level-shift center-tap potentiometer. This potentiometer is used to adjust the offset voltage of the amplifier. It is typically adjusted to manipulate the gain of the amplifier and/or to adjust the symmetry of the output.The KA358S is most commonly used in audio amplification circuits, signal buffering applications, and to amplify signals for further processing or digitization. It is also used in many instrumentation applications. The wideband capability and adjustable output make it ideal for such applications.In conclusion, the KA358S is a versatile general-purpose operational amplifier that can be used for a variety of applications. Its low cost and low-noise operation make it attractive for low-cost signal conditioning and audio amplification applications. It is also suitable for instrumentation amplifier applications, signal buffering, and wideband amplitude detection.
