MAX293ESA+T

Overview

The MAX293ESA+T is an active lowpass filter IC from Analog Devices, housed in an 8-SOIC package. It implements a switched-capacitor elliptic filter topology with an eighth-order response. The device operates within a supply voltage range of 4.5V to 16V and supports clock frequencies up to 200kHz. Key electrical parameters include a cutoff frequency of 25kHz and a power dissipation rating of 470mW. It functions as a single-channel component designed for signal processing applications requiring high attenuation.

Feature Summary

• Implements an eighth-order elliptic filter response for steep roll-off characteristics
• Utilizes switched-capacitor architecture for precise frequency control via external clock
• Provides integrated lowpass filtering functionality within a compact surface-mount package

Applications

• Signal conditioning in data acquisition systems
• Anti-aliasing filters for analog-to-digital converters
• Noise reduction in sensor interface circuits

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing. Confirm RoHS compliance status through official documentation. Ensure the supplier provides valid traceability for the Analog Devices manufacturer identification. Check current availability as distribution status may vary by region.

Selection Notes

Select this component when an eighth-order elliptic response is required for superior stopband rejection. The switched-capacitor design allows frequency adjustment via the external clock input rather than passive components. Verify that the operating supply voltage remains within the specified 4.5V to 16V range for proper operation.

Part Context

This part belongs to the MAX293 series of active filters manufactured by Analog Devices. It is classified under interface integrated circuits, specifically active filters. The device represents a specialized solution for analog signal processing tasks where high-order filtering is necessary without using discrete passive components.
