MAX293CWE+

Overview

The MAX293CWE+ is an active, low-pass, switched-capacitor filter manufactured by Analog Devices Inc. under the Maxim Integrated brand. It features an eighth-order Butterworth response with a cutoff frequency of 10 kHz. The device operates on a single 5 V supply and utilizes external clocking to define its filter characteristics. Packaged in a 16-pin SOIC, it integrates internal operational amplifiers and capacitors to realize complex filtering functions without requiring large external passive components.

Feature Summary

• Implements an eighth-order Butterworth low-pass response for steep roll-off characteristics
• Utilizes switched-capacitor architecture to minimize external component count
• Operates from a single 5 V power supply

Applications

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

Procurement Notes

Verify current availability status as this component may be subject to obsolescence or limited distribution channels. Confirm RoHS compliance details through official manufacturer documentation prior to integration into production designs.

Selection Notes

Select this component when a high-order low-pass response is required within space-constrained designs. Ensure the external clock frequency is stable, as filter performance depends directly on the ratio of clock to cutoff frequency.

Part Context

This part belongs to the MAX290-MAX295 family of switched-capacitor filters. These devices are designed to replace bulky LC filters in modern electronic systems, offering programmable cutoff frequencies via external clock signals while maintaining compact surface-mount footprints.

Replacement Considerations

Check for direct pin-compatible alternatives within the same family, such as the MAX294CWE+, which offers different cutoff frequencies. Verify that any substitute maintains the eighth-order Butterworth characteristic and compatible package dimensions.
