MAX274BCWI+

Overview

The MAX274BCWI+ is a fourth-order, continuous-time active filter manufactured by Analog Devices under the Maxim Integrated brand. It operates on a single 5V supply with a voltage range of 2.37V to 5.5V and functions within a temperature range of 0°C to +70°C. The device features a bandpass or lowpass filter type with a cutoff frequency of 150 kHz and contains one channel. It is housed in a 28-pin SO-Wide package designed for surface-mount installation.

Feature Summary

• Continuous-time architecture enabling high-frequency signal processing
• Pin-programmable configuration for flexible filter topology selection
• Single-supply operation simplifying power distribution requirements

Applications

• Wireless communication systems requiring intermediate frequency filtering
• Data acquisition systems needing anti-aliasing protection
• Instrumentation circuits demanding precise signal conditioning

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for specific ordering suffixes that may affect packaging or temperature grade. Ensure the supplier provides valid traceability documentation matching the MAX274BCWI+ designation before finalizing any acquisition.

Selection Notes

Select this component when a fourth-order response is required without external passive components. Compare against the MAX275 if an eighth-order response is needed. Verify that the 150 kHz cutoff frequency aligns with system bandwidth requirements and that the SO-Wide-28 package fits the available PCB real estate constraints.

Part Context

This part belongs to the MAX274B series of pin-programmable active filters. It shares architectural similarities with the MAX263 and MAX275 but offers distinct order and topology options. The BCWI+ suffix indicates a commercial temperature grade and lead-free construction within the broader Maxim Integrated portfolio.

Replacement Considerations

The MAX275BCWI+ serves as a compatible alternative for applications requiring higher-order filtering. Verify pin compatibility and electrical specifications before substitution. No other direct cross-model replacements are documented in official sources.
