MAX294CPA+

Overview

The MAX294CPA+ is an active filter IC featuring an elliptic, low-pass switched-capacitor architecture with an 8th-order response. It operates with a clock frequency up to 25kHz and utilizes a single supply voltage. The component is housed in an 8-pin PDIP package and is designed for precise signal filtering applications requiring high selectivity.

Feature Summary

• Elliptic low-pass switched-capacitor filter topology
• 8th-order response for steep roll-off characteristics
• Integrated clock input for frequency control

Applications

• Signal conditioning circuits
• Anti-aliasing filters in data acquisition systems
• Audio processing equipment

Procurement Notes

Verify the specific suffix designation against the manufacturer's current product selection guide to ensure compatibility with required operating conditions. Confirm that the 8-pin PDIP package matches the target PCB footprint and thermal requirements before finalizing procurement orders.

Selection Notes

Select this component when a high-order elliptic response is necessary within a switched-capacitor design. Ensure the system clock frequency aligns with the 25kHz maximum limit. Evaluate power supply constraints as the device typically requires a single supply configuration for optimal operation in standard analog signal paths.

Part Context

This part belongs to the Maxim Integrated family of active filters, specifically utilizing switched-capacitor technology. These components integrate filter functions onto a single silicon die, offering a compact alternative to discrete RC networks while maintaining precise frequency response characteristics defined by external clock signals.

Replacement Considerations

The MAX294CPA is a non-suffix variant of this component. Verify pinout and electrical specifications compatibility if substituting between the plus and non-plus versions.
