MAX274BCWI

Overview

The MAX274BCWI is a fourth-order, continuous-time active filter manufactured by Analog Devices Inc./Maxim Integrated. It operates on a single 5V supply with a voltage range of 2.37V to 5.5V. The device features a cutoff frequency of 150 kHz and supports band-pass and low-pass filter configurations. It is housed in a 28-pin SO-Wide package designed for surface-mount installation. The component functions within an operating temperature range of 0°C to +70°C.

Feature Summary

Continuous-time architecture enabling real-time signal processing without sampling delays
Single-supply operation simplifying power distribution in portable systems
Configurable filter responses including band-pass and low-pass topologies

Applications

Subterranean cable detection systems
Signal conditioning for communication receivers
Anti-aliasing filters in data acquisition chains

Procurement Notes

Verify the specific suffix 'C' against the official datasheet to confirm the commercial temperature grade and performance specifications. Ensure the SO-Wide-28 package dimensions match the target PCB footprint requirements before finalizing procurement decisions.

Selection Notes

Select this component when a fourth-order response is required without digital control overhead. Compare the 150 kHz cutoff frequency against system bandwidth needs. Verify that the single-supply requirement aligns with available power rails in the design.

Part Context

This part belongs to the MAX274B series of continuous-time active filters. It shares architectural similarities with the MAX275 but differs in order and configuration options. The series is designed for applications requiring precise analog filtering with minimal external components.

Replacement Considerations

Check for direct pin-compatible alternatives within the MAX274 family. Verify if higher-order variants or different cutoff frequencies from the same manufacturer meet the design requirements without circuit redesign.
