BA4558F-E2 Application Field and Working Principle

Introduction

The BA4558F-E2 is a three-terminal low noise operational amplifier manufactured by Rohm Corporation. The BA4558F-E2 falls into the category of linear amplifiers, specifically the instrumentation, operational amplifiers (op amps), and buffer amplifiers. This device has a wide variety of applications, including signal conditioning, signal filtering, signal processing, and audio applications. It is also used in high-end audio, medical, and industrial equipment.

Application Fields

The BA4558F-E2 is suitable for a variety of different applications, such as high-end audio equipment, medical devices, and industrial control systems. It is an ideal choice for signal conditioning, signal filtering, and signal processing applications. In particular, it is used in audio equipment such as CD players, amplifiers, and speakers. It is also used in medical devices such as blood pressure monitors, monitors for measuring ECG, and other medical instruments. Its low noise level makes it suitable for use in industrial applications, particularly for measuring and monitoring signals.

Features

The BA4558F-E2 features a low noise level, high gain bandwidth product, high frequency response, high output voltage, and low distortion. It is a low power device, with a maximum current consumption of just 10 mA. It is also a highly reliable device, with an expected lifetime of over 20 years of use.

Design Considerations

When designing a system using the BA4558F-E2, it is important to consider factors such as power supply voltage, power supply ripple, quiescent current, and feedback resistors. The power supply voltage should be chosen so as to ensure proper operation of the BA4558F-E2. Excessive power supply ripple should be avoided, as this can affect the linearity of the output signal. It is important to ensure that the quiescent current is chosen correctly, as this can affect the gain and frequency response of the device. The feedback resistors should also be chosen correctly, to ensure the desired gain and frequency response.

Working Principle

The BA4558F-E2 is an operational amplifier (op amp) and it works according to the classical inverting amplifier configuration. It takes in an input signal as a voltage difference between its two input terminals (non-inverting and inverting). This signal is amplified by the op amp according to its open-loop gain, undergoes phase inversion and is then output as a voltage difference between its +Vout and -Vout terminals. The gain of this device is set by a feedback network, made of two resistors connected between the output and the inverting input, as well as two capacitors connected between the two inputs.

Conclusion

The BA4558F-E2 is a three-terminal low noise operational amplifier manufactured by Rohm Corporation. It has a wide range of applications in audio, medical and industrial equipment and provides excellent performance, with a low noise level, high gain bandwidth product, high frequency response, high output voltage, and low distortion. It works according to the classical inverting amplifier configuration, and its gain is set by a feedback network made of two resistors and two capacitors.
