Introduction
MAX267AENG is a family of three-terminal active filters designed to provide features such as low pass and high pass filtering, voltage gain, senstivity adjustment and antenna coupling. These filters are based on a two-stage structure of active lowpass and highpass filters where each stage has its own active filter. The MAX267AENG can be used for various applications such as automotive audio systems, PLLs, and speech recognition.
Application Field
The MAX267AENG Active Filter is mainly intended for design use in automotive audio systems. The filter removes unwanted high-frequency noise from the audio signal and allows the signal to pass through with much less distortion. It also provides an adjustable gain control which can be used to tailor the sound of a system. The filter provides a low pass filter, a high pass filter, a voltage gain adjustment, and antenna coupling.
The filter is also very useful for PLL (phase-locked loop) applications as it can provide a wide adjustable frequency range while ensuring stability and accuracy. In speech recognition applications, the filter can reduce background noise and improve system performance.
Working Principle
The MAX267AENG Active Filter works by passing the audio signal through two separate filters. The first filter is a high-pass filter, which removes all signals with frequencies lower than the cutoff frequency. The second filter is a low-pass filter, which removes all signals with frequencies higher than the cutoff frequency. By controlling these two cutoff frequencies with the gain control, the overall frequency range of the filter can be adjusted.
The filter also offers an adjustable gain control which can be used to increase or decrease the overall level of the audio signal. This can be used to tailor the sound of the system or to compensate for differences between the source and the target audio system. The filter also includes a coupling capacitance at the input, which helps to reduce RF interference.
Conclusion
The MAX267AENG Active Filter is a versatile active filter that provides low pass and high pass filtering, voltage gain, senstivity adjustment, and antenna coupling. It is most commonly used for automotive audio systems and PLLs, but can also be used for speech recognition applications. It provides an adjustable cutoff frequency and adjustable gain that can be used to tailor the sound of the system. The filter also includes a coupling capacitance at the input, which helps to reduce RF interference.
