Maxim Integrated MAX297CWE-T: High-Performance, 8th-Order, Lowpass, Elliptic, Switched-Capacitor Filters

The MAX297CWE-T from Maxim Integrated is a compact, high-performance 8th-order lowpass elliptic filter that is part of a family of monolithic, switched-capacitor filters. This device is specifically designed to provide a sharp cutoff with low noise, making it ideal for a variety of signal processing applications. With the MAX297CWE-T, engineers can achieve precise filtering characteristics that are often required in telecommunications, data acquisition, and audio systems.

This filter operates from a single +5V supply, and it features a user-selectable cutoff frequency that can be set from 0.1Hz to 25kHz, making it extremely versatile for different design requirements. The MAX297CWE-T's 8th-order elliptic lowpass response ensures excellent selectivity and a fast transition from passband to stopband, which is critical in applications where the suppression of unwanted frequencies is crucial.

The device comes in a 16-pin SOIC package, which is suitable for space-constrained applications. Its small footprint allows for integration into compact designs without sacrificing performance. Additionally, the MAX297CWE-T's low power consumption makes it a great choice for portable and battery-powered devices, where power efficiency is a key consideration.

One of the standout features of the MAX297CWE-T is its clock-tuning range, which is 100:1, allowing for a wide range of filter characteristics. This flexibility is further enhanced by the fact that the device can be put into a low-power mode, reducing power consumption when high performance is not necessary.

The MAX297CWE-T also provides a shutdown mode, reducing the supply current to 0.2µA, which is ideal for power-sensitive applications. This feature ensures that the device can be effectively integrated into systems where power management is critical.

In summary, the MAX297CWE-T from Maxim Integrated is a highly versatile, low-noise, 8th-order lowpass elliptic filter that offers designers a compact solution for a wide range of filtering applications. Its user-selectable cutoff frequency, low power consumption, and shutdown feature make it a valuable component for any signal processing design.
