Maxim Integrated MAX7410EUA+T - 5th-Order, Lowpass, Elliptic, Switched-Capacitor Filters

The MAX7410EUA+T from Maxim Integrated is a highly sophisticated, 5th-order, lowpass, elliptic, switched-capacitor filter that significantly simplifies the design of high-performance signal conditioning circuits. This compact component, available in an 8-pin µMAX package, is designed for applications requiring a sharp roll-off with low ripple in the passband and a fast transition to the stopband.

With a fixed frequency response that is factory set at 30kHz, the MAX7410EUA+T provides a precise filtering solution that is ideal for anti-aliasing or post-DAC filtering applications. The filter does not require any external components for setting the corner frequency, which makes it an excellent choice for space-constrained designs where board real estate is at a premium.

This device operates from a single +5V supply, making it suitable for a variety of digital and analog systems. Its low power consumption is particularly beneficial for portable and battery-powered devices, ensuring minimal impact on the overall power budget of the system. The MAX7410EUA+T also features a shutdown mode that reduces power consumption further when the filter is not in use.

The MAX7410EUA+T boasts a Clock-to-Corner Frequency ratio (f<sub>CLK/f<sub>C) of 100:1, providing designers with the flexibility to choose an appropriate clock source. The device's high selectivity and deep stopband attenuation of -65dB make it an excellent choice for applications where suppression of unwanted frequencies is critical.

Integration into existing designs is straightforward, thanks to the MAX7410EUA+T's user-friendly interface. It is fully specified over the extended industrial temperature range of -40°C to +85°C, which ensures reliable performance in harsh environments.

In summary, the Maxim Integrated MAX7410EUA+T is a versatile and reliable component that offers superior filtering capabilities for a wide range of applications. Its ease of use, combined with its small footprint, makes it an ideal choice for designers looking to enhance their signal processing systems without compromising on space or power efficiency.
