Maxim Integrated MAX7403CSA+T Low-Pass Filter

The MAX7403CSA+T from Maxim Integrated is a high-performance, 8th-order, low-pass, elliptic, switched-capacitor filter that significantly reduces the component count in digital signal processing applications. This precision filter IC is well-suited for anti-aliasing and anti-imaging applications, as well as for signal conditioning tasks in a wide range of products, from medical devices to industrial systems.

Designed with advanced CMOS technology, the MAX7403CSA+T operates with a single +5V power supply, making it an energy-efficient choice for portable devices. Its clock-tunable cutoff frequency allows for flexibility in design, enabling users to set the desired frequency response for their specific application by simply adjusting the external clock frequency.

One of the standout features of the MAX7403CSA+T is its sharp cutoff characteristic, which provides excellent selectivity and deep attenuation of out-of-band signals. With a transition ratio of 1.6:1, this filter ensures that signals within the passband are processed with minimal distortion, while unwanted frequencies are effectively suppressed.

The device comes in a compact SOP (Small Outline Package), with the “T” in its part number indicating tape and reel packaging, which is ideal for automated manufacturing processes. The MAX7403CSA+T is designed for easy integration into a variety of circuits, requiring minimal external components, which helps to simplify PCB layout and reduce overall design time.

Key specifications of the MAX7403CSA+T include:

• 8th-order low-pass elliptic filter
• Single +5V supply operation
• Low power consumption
• User-selectable clock-tunable cutoff frequency
• Sharp roll-off with a transition ratio of 1.6:1
• Low output offset: ±5mV
• Compact SOP-8 package

Whether you're designing a high-fidelity audio system, a sensitive measurement instrument, or any other application requiring precise signal filtering, the MAX7403CSA+T offers a reliable and efficient solution. Maxim Integrated's commitment to quality ensures that this filter IC will meet the rigorous demands of modern electronic designs.
