MAX275BEWP+

Overview

The MAX275BEWP+ is a low-power, fourth-order, continuous-time, low-pass filter manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates on a single 2.7V to 5.5V supply and features a pin-programmable cutoff frequency range from 10kHz to 400kHz. The device integrates four biquad sections with an external capacitor network to realize complex filter responses. Key electrical parameters include a gain bandwidth product of 3MHz, a maximum input offset voltage of 10mV, and a quiescent current of 1.6mA per amplifier. It is housed in a 28-pin narrow SOIC package.

Feature Summary

• Pin-programmable cutoff frequency selection via external resistors
• Integrated fourth-order continuous-time architecture
• Single-supply operation capability

Applications

• Video signal processing
• Audio filtering
• Data acquisition systems

Procurement Notes

Verify the specific suffix 'BEWP+' against the official datasheet to confirm temperature grade and packaging type. Ensure compatibility with the required cutoff frequency programming components. Confirm RoHS compliance status through the manufacturer's documentation before finalizing procurement.

Selection Notes

Select this component when a compact, low-power solution for video or audio filtering is required. Compare the 3MHz gain bandwidth product against system requirements. Evaluate the need for external capacitors versus fully integrated alternatives if space constraints are critical.

Part Context

This part belongs to the MAX274/MAX275 family of continuous-time filters. It serves as the fourth-order variant within the series, offering higher attenuation than the second-order MAX274. Both devices share identical pinouts and programming methods.

Replacement Considerations

The MAX274 is a compatible alternative offering second-order filtering performance. Verify that the reduced order meets the system's stopband rejection requirements before substituting.
