MAX275BCPP

Overview

The MAX275BCPP is a fourth-order continuous-time active low-pass filter manufactured by Analog Devices Inc./Maxim Integrated. It operates on a single +5V supply and features a cutoff frequency of 100kHz with a Butterworth response. The device integrates four operational amplifiers and external capacitors to realize the filter function, eliminating the need for inductors or resistors. It provides high linearity and low distortion, making it suitable for precision signal processing applications requiring compact size and stable performance across temperature variations.

Feature Summary

• Integrates four op amps and capacitor network for complete filter realization
• Single-supply operation simplifies power requirements
• Butterworth response ensures flat passband characteristics
• Compact surface-mount package reduces board space

Applications

• Anti-aliasing filters in data acquisition systems
• Signal conditioning for sensor interfaces
• Audio processing circuits requiring low distortion
• Instrumentation front-end filtering

Procurement Notes

Verify component authenticity through authorized distributors. Check datasheet revision history for updates. Confirm package type matches design requirements. Ensure environmental compliance aligns with project specifications. Validate supplier credentials before purchase.

Selection Notes

Compare cutoff frequency requirements against application needs. Evaluate power supply constraints for single vs dual supply options. Consider package availability for manufacturing processes. Assess thermal performance under operating conditions. Verify compatibility with existing circuit topology.

Part Context

Part of the MAX274/MAX275 family of continuous-time active filters. Offers alternative filter responses including Chebyshev and Bessel variants within the same series. Designed for integration into analog signal chains where discrete components would increase complexity.

Replacement Considerations

MAX274BMYG offers similar functionality with different package configuration. MAX275AEPP provides equivalent electrical characteristics in alternative housing. Verify pinout compatibility before substitution.
