MAX274BENG+

Overview

The MAX274BENG+ is a monolithic, continuous-time active filter manufactured by Analog Devices under the Maxim Integrated brand. It integrates four independent second-order sections to implement fourth- or eighth-order lowpass, bandpass, highpass, or notch responses. The device operates on a single 5V supply with a cutoff frequency range from 10Hz to 150kHz, controlled by an external clock. Key electrical parameters include a maximum power supply voltage of 5.5V and a minimum operating voltage of 2.37V. It functions within a temperature range of -40°C to +85°C and utilizes a UCSP package.

Feature Summary

• Integrates four independent second-order sections for flexible filter configuration
• Supports multiple response types including lowpass, bandpass, highpass, and notch
• Operates on a single 5V power supply
• Features externally programmable cutoff frequencies via clock input

Applications

• Anti-aliasing filters in data acquisition systems
• Signal conditioning for power parameter measurement devices
• Channel selection in communication receivers

Procurement Notes

Verify component authenticity through authorized distributors or official manufacturer channels. Confirm that the ordering suffix matches the required temperature grade and package type. Ensure compliance with RoHS directives and check for any specific handling requirements during storage and assembly.

Selection Notes

Select this component when designing circuits requiring integrated continuous-time filtering without external passive components. Consider the available cutoff frequency range and the need for precise clock control. Evaluate the package constraints and thermal performance against the application's environmental conditions.

Part Context

This part belongs to the MAX274/MAX275 family of continuous-time active filters. These devices are designed to replace bulky discrete RC networks, offering a compact solution for signal processing tasks. The family is known for its ease of use and integration capabilities in analog front-end designs.

Replacement Considerations

Direct substitutes may include other models from the MAX274 series with compatible packages. Verify pin compatibility and electrical specifications before replacement. Consult the manufacturer's documentation for updated alternatives if the current part is discontinued.
