Maxim Integrated MAX7403CPA Low-Pass Filter

The MAX7403CPA is a precision, 8th-order, low-pass filter designed by Maxim Integrated to provide optimal performance for noise reduction in digital and analog systems. This filter is part of Maxim's MAX7400 series of switched-capacitor filters that offer a wide range of cutoff frequencies, making them highly versatile for various applications.

Engineered with a fixed 3dB cutoff frequency set at 5kHz, the MAX7403CPA stands out for its sharp roll-off characteristics and excellent stopband attenuation. This makes it an ideal choice for anti-aliasing applications, DAC smoothing filters, or any other application that requires a clean and precise low-pass filter response.

The device operates from a single +5V supply, which simplifies the power supply design and ensures compatibility with a wide range of digital systems. Additionally, the MAX7403CPA features a low-pass filter response that is free from clock feedthrough and ripple, providing a clean and stable output signal.

With its compact 8-pin DIP package, the MAX7403CPA is easy to integrate into existing designs without requiring significant board space. It also offers a CMOS process construction, ensuring high reliability and a long operational lifespan.
