The MAX281ACP from Maxim Integrated is a precision active filter designed to deliver high-performance filtering for a wide range of applications. This integrated circuit provides a flexible solution for designers looking to implement low-noise, high-frequency filtering in their systems without the complexity of designing discrete filter circuits.

The MAX281ACP is part of Maxim's MAX280–MAX282 family of monolithic, continuous-time, active filters. These filters are capable of providing low-pass, high-pass, band-pass, and notch functions without the need for any external components, making them an ideal choice for space-constrained applications.

This high-quality filter operates in a single-supply voltage range of +4.5V to +11V or dual supplies of ±2.25V to ±5.5V, providing the versatility needed for various electronic devices. Its low-noise performance and high-frequency capabilities, with a clock-to-corner frequency ratio of 100:1, make it suitable for applications in data acquisition, signal processing, and audio systems.

The MAX281ACP offers a filter response that is programmable via an external clock or can be tuned by an external resistor. This programmability allows for precise adjustment of the filter's frequency response to meet the specific needs of an application. Additionally, the device features a low total harmonic distortion (THD) of 0.01%, ensuring the integrity of the signal is maintained through the filtering process.

The compact 8-pin DIP or SO package of the MAX281ACP makes it easy to integrate into existing designs. Its robust design includes a dynamic range of 86dB and an operating temperature range of 0°C to +70°C, which is suitable for most commercial-grade applications.

Whether you're designing a high-fidelity audio system, a sensitive instrumentation setup, or any other system requiring clean signal processing, the MAX281ACP from Maxim Integrated provides a high-quality, reliable solution for your active filtering needs.
