MAX297CWE+T

Overview

The MAX297CWE+T is an eighth-order lowpass switched-capacitor active filter manufactured by Analog Devices Inc./Maxim Integrated. It operates with a single supply voltage ranging from 4.75 V to 11 V, typically utilizing a 5 V source. The device features a cutoff frequency of 25 kHz and is housed in a 16-pin SOIC package designed for surface-mount installation. It functions within a temperature range of 0°C to +70°C.

Feature Summary

• Provides high-order filtering characteristics using switched-capacitor technology
• Operates on a single power supply rail
• Includes external clock input capability for frequency control

Applications

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

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for obsolescence notices. Ensure the specific suffix matches design requirements before procurement.

Selection Notes

Evaluate the required clock frequency relative to the desired cutoff frequency. Ensure the operating voltage range aligns with system power rails. Consider thermal performance within the specified industrial temperature limits during circuit design.

Part Context

This component belongs to the MAX29x series of switched-capacitor filters. These devices integrate multiple filter stages into a single IC, reducing board space compared to discrete RC solutions. The MAX297 variant specifically offers eighth-order response for superior selectivity.

Replacement Considerations

MAX297CWE-T is a compatible alternative within the same product family.
