Maxim Integrated MAX7401ESA 8th-Order Lowpass, Elliptic, Switched-Capacitor Filters

The MAX7401ESA from Maxim Integrated is a compact, high-performance 8th-order lowpass elliptic switched-capacitor filter that significantly reduces the complexity of signal conditioning in a wide array of applications. This precision filter is encapsulated in an 8-pin SOIC package, designed to deliver a sharp cutoff with an excellent stopband attenuation, making it an ideal choice for anti-aliasing or post-DAC filtering applications.

With its fixed cutoff frequency set at 25kHz, the MAX7401ESA offers a precise filtering solution that is easy to implement, as it requires no external components for set-up. This makes it a highly cost-effective option for designers looking to minimize the size and complexity of their circuit designs without compromising on performance.

The device operates from a single +5V supply, which allows for a straightforward power management within systems that have a 5V rail available. The MAX7401ESA boasts a low power consumption, making it suitable for battery-powered devices where power efficiency is crucial. Its clock-tunable feature enables the adjustment of the cutoff frequency over a wide range by simply varying the clock frequency, providing additional flexibility to the end-user.

Another standout feature of the MAX7401ESA is its low THD (Total Harmonic Distortion), which ensures that the signal integrity is maintained even under full-scale input conditions. This is particularly important in audio applications and precision measurement equipment where signal fidelity is paramount.

The robust design of the MAX7401ESA also includes a clock input that is TTL/CMOS compatible, allowing for easy integration into digital systems. Additionally, the device boasts a sharp roll-off characteristic and a high degree of stopband attenuation, which ensures that unwanted frequencies are effectively blocked from passing through the filter.

In summary, the MAX7401ESA from Maxim Integrated is a highly reliable and efficient solution for designers who require a precision lowpass filter with low power consumption, easy integration, and excellent signal processing characteristics. Whether it's used in audio processing, data acquisition, or any other application that demands clean signal conditioning, the MAX7401ESA stands out as a top-performing component in its class.
