Active filters are essential components in many electronic circuits. They help the circuits to achieve specific requirements when the circuits require more complex filtering from the signals that are received from the outside environment. Active filters are usually used along with passive filters in applications such as pre-amps, audio amplifiers, equalizers and other specialized applications. MAX268BCNG active filter is a versatile filter IC which can be used for several applications. Let’s discuss the application field and working principle of the MAX268BCNG active filter.
Application Fields
The MAX268BCNG active filter is mainly used for the implementation of low noise audio pre-amps, microphone pre-amps and acoustic echo cancellation applications. The MAX268BCNG is a high performance active filter that is ideally suited for these applications. The filter offers excellent noise performance and is able to provide high quality sound by suppressing harmful interference and noise. The device is also suitable for other applications that require stringent noise performance while being able to provide low output impedance.
The device is well-suited for the applications that require removing noise from audio signals like those present in professional-grade audio recording and post-production applications. It is also capable of filtering out high frequency noise in applications such as automated voice recognition, hearing aid testing and medical equipment. The MAX268BCNG is designed to work with a system clock frequency ranging from 10MHz to 50MHz and also supports a wide range of audio and control signals.
Working Principle
The MAX268BCNG active filter is mainly composed of a low pass filter, band-pass filter, high pass filter and a noise-canceling topology. The low pass filter is used to suppress the high frequency noise components which are undesirable in certain applications. The band-pass filter is used to filter out unwanted signals in the mid-frequency range. The high pass filter is used to reduce the low-frequency noises which is necessary for many audio applications. The last part of the active filter comprises of a noise-canceling topology which helps in reducing the unwanted noise in the signal path without distorting the actual signal which is to be processed.
The device is able to reduce the high frequency noises that are present in the signal while keeping the mid and low frequency components intact. The active filter is also capable of being programmed in order to obtain the best sounding signal with the lowest distortion. The device is highly efficient and consumes very low power. It is capable of operating within a temperature range of -20°C to +85°C and has a high level of immunity due to the built in ESD protection.
Conclusion
The MAX268BCNG active filter is a versatile and high performance device which is used in a wide range of applications that require low noise performance and high signal to noise ratio. It is capable of providing excellent sound quality by suppressing unwanted noise and interference. The device is highly efficient and consumes very low power. It is designed to work with a range of audio and control signals and also supports a wide range of operating temperatures. The MAX268BCNG active filter offers excellent performance and is ideal for several audio and acoustic applications.
