EL8202IY Application Field and Working Principle

The EL8202IY is an integrated circuit (IC) designed to amplify signals, used primarily in instrumentation, operational amplifiers, buffer amplifiers and linear amplifiers. It is a two-stage amplifier, with a differential input that provides high common mode rejection. It also features a gain-setting pin, which allows the gain to be set to 0, 1, or 2.

Features of EL8202IY

The EL8202IY features several advanced design techniques that allow for ultralow distortion and headroom, as well as low noise and low input and output bias current. It has a wide bandwidth of up to 100MHz, a fast settling time of 0.1µs, and a typical power supply rejection ratio (PSRR) of 80dB. It also has a common mode input range of -7V to +7V and its quiescent current draw is typically 20mA. Finally, its quiescent output voltage is adjustable within ±5V.

Application Field

The EL8202IQ is commonly used in applications such as portable audio, high-end audio, microphone preamplification and instrumentation in medical and industrial fields. It can also be used as a buffer amplifier for low power applications, such as audio and video systems, as well as for buffering and amplifying differential signals for medical and industrial systems. Additionally, high gain, low noise and low distortion make the EL8202IQ an ideal amplifier for data conversion, communications and control systems.

Working Principle

The EL8202IQ is a two-stage amplifier composed of a differential input and a gain-setting pin. The gain-setting pin is used to set the gain to 0, 1, or 2. The first stage of the amplifier is a differential input stage, which provides high common mode rejection, as well as very low noise and low distortion. The second stage is a unity gain operational amplifier, which provides further noise and distortion reduction, as well as high performance. Finally, the output stage is adjustable, and can be used to adjust the output voltage within ±5V.

Conclusion

The EL8202IQ is an advanced, high-performance IC designed for instrumentation, operational amplifiers, buffer amplifiers and linear amplifiers. Its wide bandwidth and low noise and distortion make it an ideal choice for audio and video systems, as well as for medical and industrial systems. Furthermore, its adjustable output stage allows for flexibility in designing applications, making it a very versatile IC for a wide range of applications.
