Product Overview: MAX7480ESA+T from Maxim Integrated

The MAX7480ESA+T is a high-performance, 8th-order, lowpass, elliptic, switched-capacitor filter that significantly reduces the component count in digital signal processing applications. Manufactured by Maxim Integrated, a leader in analog and mixed-signal engineering, this filter is designed to operate with a single +5V supply, making it ideal for a wide array of applications such as anti-aliasing, post-DAC filtering, and data acquisition systems.

With a fixed cutoff frequency set at 100kHz, the MAX7480ESA+T provides a sharp transition band and an excellent stopband attenuation of 80dB, ensuring that unwanted high-frequency noise is effectively suppressed. The filter's 8th-order elliptic response gives it a steeper roll-off compared to Butterworth and Chebyshev filters, which makes it a perfect choice for applications requiring a stringent filter characteristic with minimal signal distortion.

One of the key features of the MAX7480ESA+T is its user-friendly interface. It requires no external components for setting the clock frequency, as it comes with an internal clock oscillator that can be adjusted with a single external capacitor. This simplifies the design and reduces the time to market for products incorporating this filter. Additionally, the device offers a clock-to-corner frequency ratio of 100:1, providing flexibility in various applications.

The MAX7480ESA+T is available in a compact 8-pin SO package, making it suitable for space-constrained designs. The device also features a shutdown mode, which reduces the power consumption significantly when the filter is not in use, thus enhancing the power efficiency of the overall system.

Designed with the needs of modern electronics in mind, the MAX7480ESA+T offers a robust solution for digital signal filtering. Its combination of high performance, ease of use, and power efficiency makes it an excellent choice for designers seeking to optimize their signal processing applications without compromising on quality or functionality.
