MAX274BCNG+

Overview

The MAX274BCNG+ is a fourth-order, continuous-time active filter manufactured by Analog Devices under the Maxim Integrated brand. It operates within a supply voltage range of 4.74V to 5.5V and features a cutoff frequency of 150kHz. The component utilizes an SO-Wide-28 surface-mount package and supports band-pass and low-pass filtering configurations. Designed for commercial temperature ranges from 0°C to +70°C, it integrates four second-order sections to achieve high performance without requiring external tuning components.

Feature Summary

• Integrates four second-order sections into a single monolithic chip
• Eliminates the need for external tuning components
• Supports simultaneous band-pass and low-pass filtering outputs

Applications

• Wireless communication systems
• Data acquisition front ends
• Instrumentation signal conditioning

Procurement Notes

Verify the specific suffix 'CNG+' against official documentation to confirm lead-free status and RoHS compliance. Confirm that the package type matches the required PCB footprint. Ensure the operating environment remains within the specified commercial temperature limits.

Selection Notes

Select this component when a compact solution for fourth-order filtering is required. Verify that the 150kHz cutoff frequency aligns with system bandwidth requirements. Consider the SO-Wide-28 package dimensions during layout planning.

Part Context

This part belongs to the MAX274B series of continuous-time active filters. It shares architectural similarities with the MAX275 but differs in pinout configuration. The device represents a standard solution for analog signal processing in mixed-signal environments.

Replacement Considerations

The MAX275 serves as a functional alternative with identical electrical characteristics but utilizes a different pinout arrangement. Verify pin compatibility before substituting.
