MAX275BCWP+

Overview

The MAX275BCWP+ 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 two capacitors within a 20-pin narrow plastic DIP package. Key electrical specifications include a maximum power supply voltage of 6V, an operating temperature range from -40°C to +85°C, and a typical quiescent current of 3mA per amplifier.

Feature Summary

• Integrates four op amps and two capacitors for complete fourth-order filtering
• Supports single-supply operation at +5V
• Provides selectable Butterworth or Chebyshev frequency responses

Applications

• Data acquisition systems requiring anti-aliasing filters
• Instrumentation signal conditioning
• Communication channel selection

Procurement Notes

Verify the component authenticity through official Analog Devices channels or authorized distributors. Confirm that the ordering suffix matches the specific package and temperature grade requirements for your design. Ensure compliance with RoHS directives as indicated in the product documentation before finalizing procurement orders.

Selection Notes

Select this component when a compact, low-power solution for fourth-order filtering is required. Compare the 100kHz cutoff frequency against system bandwidth needs. Verify that the narrow DIP package fits the available PCB real estate and that the single-supply architecture aligns with the target power rails.

Part Context

This part belongs to the MAX274/MAX275 family of continuous-time active filters. These devices are designed to replace discrete RC ladder networks, reducing board space and simplifying design. The MAX275 specifically offers a 100kHz cutoff frequency, distinguishing it from other variants in the series with different frequency ratings.

Replacement Considerations

Direct replacements include the MAX274BCWP+ for identical functionality with a different cutoff frequency. Cross-reference pinouts and electrical characteristics carefully to ensure compatibility with existing circuit designs without requiring schematic modifications.
