MAX294CSA+

Overview

The MAX294CSA+ is an active filter integrated circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It implements an eighth-order, lowpass, elliptic response using switched-capacitor technology. The device operates with a cutoff frequency of 25kHz and is housed in an 8-SOIC package. This component is designed for precision signal processing applications requiring high attenuation and sharp roll-off characteristics within a compact surface-mount form factor.

Feature Summary

• Implements an eighth-order elliptic lowpass filter response
• Utilizes switched-capacitor technology for precise frequency control
• Provides high attenuation and sharp roll-off characteristics

Applications

• Precision signal conditioning circuits
• Anti-aliasing filters in data acquisition systems
• Noise reduction in analog sensor interfaces

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and lot traceability upon receipt. Ensure storage conditions meet specified humidity and temperature limits to prevent package degradation. Validate pinout compatibility with target PCB footprint before assembly.

Selection Notes

Select this component when an eighth-order elliptic response is required for superior stopband rejection. Consider the 25kHz cutoff frequency relative to the signal bandwidth. Evaluate the switched-capacitor nature against clock noise sensitivity in the application environment. Compare against lower-order alternatives if less stringent filtering is acceptable.

Part Context

This part belongs to the MAX29x series of active filters from Maxim Integrated. These devices integrate switched-capacitor filter functions on a single chip, eliminating the need for external capacitors and resistors typically required in discrete active filter designs. The series offers various order and response options for different signal processing needs.
