MAX293CWE+T

Overview

The MAX293CWE+T is an active filter component manufactured by Analog Devices Inc./Maxim Integrated. It functions as an 8th-order lowpass elliptic switched-capacitor filter. The device operates with a single supply voltage ranging from 4.75 V to 11 V, typically utilizing a 5 V operating voltage. It features a cutoff frequency of 25 kHz and contains one channel. The unit is housed in a SOIC-16 package designed for surface mount installation. It supports operation within a temperature range of 0°C to +70°C.

Feature Summary

• Implements 8th-order elliptic lowpass filtering characteristics using switched-capacitor technology.
• Provides precise frequency control via external clock input relative to the cutoff frequency.
• Integrates all necessary filter components into a single monolithic IC structure.

Applications

• Signal conditioning in data acquisition systems requiring high selectivity.
• Anti-aliasing filters in analog-to-digital conversion interfaces.
• Audio processing circuits demanding steep roll-off characteristics.

Procurement Notes

Verify the specific suffix 'CWE+T' against official manufacturer documentation to confirm package type, temperature grade, and tape-and-reel packaging details. Ensure compatibility with existing board layouts regarding the SOIC-16 footprint and pin configuration before procurement.

Selection Notes

Select this component when an 8th-order elliptic response is required for sharp attenuation. Confirm that the system can provide a stable clock signal approximately 50 times the desired cutoff frequency. Verify that the single-supply voltage range aligns with the available power rails in the target application design.

Part Context

This part belongs to the MAX292/MAX293 family of switched-capacitor filters. These devices are designed to replace complex discrete RC networks. The MAX293 specifically offers an elliptic response, distinguishing it from the maximally flat response of related models like the MAX292.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Cross-reference with MAX292 variants only if a different filter response curve is acceptable.
