MAX295CSA

Overview

The MAX295CSA is an active, eighth-order lowpass switched-capacitor filter manufactured by Analog Devices Inc./Maxim Integrated. It operates on a single 5 V supply and features a cutoff frequency of 50 kHz. The device is housed in an 8-lead SOIC package and supports surface-mount installation. It functions within a temperature range of -40°C to +85°C and includes an external clock input for frequency tuning.

Feature Summary

• Provides high-performance filtering using switched-capacitor technology without requiring external capacitors or inductors.
• Features a single-supply architecture compatible with standard 5 V logic systems.
• Offers precise frequency control through an external clock interface.

Applications

• Signal conditioning in data acquisition systems
• Anti-aliasing filters for analog-to-digital converters
• Audio processing circuits

Procurement Notes

Verify the specific suffix 'CSA' against official datasheets to confirm package type and commercial temperature rating. Ensure compatibility with existing PCB footprints for SOIC-8 packages. Confirm availability status as distribution channels may vary.

Selection Notes

Select this component when an eighth-order response is required in a compact form factor. Compare against other members of the MAX29x family if different cutoff frequencies or order specifications are needed. Verify that the external clock source meets the stability requirements specified in the electrical characteristics.

Part Context

This part belongs to the MAX29x series of switched-capacitor filters, which integrate multiple biquad sections to achieve higher-order responses. These devices were designed to simplify the implementation of complex analog filtering functions in mixed-signal applications.

Replacement Considerations

Check for direct pin-compatible alternatives within the same product line. Verify that any substitute maintains the same cutoff frequency and package dimensions.
