Maxim Integrated MAX7420CUA+ Product Overview

The MAX7420CUA+ is a high-performance, 8-pin, single-channel, low-pass filter designed and manufactured by Maxim Integrated. This filter is part of Maxim's MAX7420/MAX7421 family, which utilizes a proprietary CMOS process to offer high signal processing quality with minimal power consumption. The MAX7420CUA+ is specifically crafted to cater to applications requiring a sharp roll-off and low-noise performance.

Key Features

• Elliptic Low-Pass Filter: The device features a 5th-order filter response, ensuring a steep attenuation curve beyond the cutoff frequency, which is ideal for signal processing applications that require precise frequency delineation.
• Low Power Consumption: With its advanced design, the MAX7420CUA+ operates with a low current draw, making it suitable for battery-powered devices and applications where power efficiency is critical.
• Fixed Cutoff Frequency: The filter comes with a factory-set cutoff frequency, providing users with a reliable and consistent filter response without the need for external components or tuning.
• Single-Supply Operation: The device can operate from a single +5V supply, simplifying power supply design and reducing system complexity.
• Rail-to-Rail Outputs: It offers rail-to-rail outputs, which maximize dynamic range and are particularly useful in low-voltage applications.
• Compact Package: Housed in a small 8-pin µMAX package, the MAX7420CUA+ is designed to save space on the PCB, making it an excellent choice for space-constrained applications.
