Maxim Integrated MAX7414EUA+T - 5th-Order, Lowpass, Elliptic, Switched-Capacitor Filters

The MAX7414EUA+T from Maxim Integrated is a high-performance, 5th-order, lowpass, elliptic filter that operates as a switched-capacitor filter with a user-selectable fixed frequency. This integrated circuit is designed to offer a precise filtering solution for a variety of signal processing applications. The MAX7414EUA+T comes in a compact 8-pin µMAX package, making it ideal for space-constrained applications.

Characterized by its sharp roll-off and excellent stopband attenuation, the MAX7414EUA+T filter provides a single-pole response with a -3dB frequency at 100kHz. This makes it particularly suitable for anti-aliasing applications or for removing high-frequency noise in digital and communication systems. The filter's fixed operating frequency can be set by connecting a clock signal, or it can be driven by an external clock source for added flexibility.

Featuring a low-power consumption design, the MAX7414EUA+T operates over a wide supply voltage range of 2.7V to 5.5V, making it compatible with most standard logic levels and suitable for battery-powered devices. The device also includes a shutdown mode that reduces power consumption to 0.2µA (typ), further extending battery life in portable applications.

The MAX7414EUA+T is designed for ease of use, requiring no external components for filter setting. This plug-and-play aspect, combined with its high-performance filtering capabilities, makes it a popular choice for designers in the audio processing, data acquisition, and industrial control sectors. Additionally, it is also used in applications such as medical instrumentation, A/D converter anti-aliasing, and DAC smoothing filters.

Maxim Integrated's commitment to reliability and performance is evident in the MAX7414EUA+T, which is fully specified over the extended industrial temperature range (-40°C to +85°C). This ensures stable operation even in harsh environmental conditions, making it a reliable choice for mission-critical applications.

In summary, the MAX7414EUA+T from Maxim Integrated is a versatile and efficient solution for implementing high-quality, lowpass filtering in a range of electronic systems. Its compact size, low power consumption, and ease of integration make it an excellent choice for designers looking to enhance their signal processing capabilities.
