MAX297CWE+

Overview

The MAX297CWE+ is an eighth-order low-pass switched-capacitor filter manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates on a single positive supply voltage ranging from 4.5 V to 12 V, with a maximum power dissipation of 600 mW. The device features a programmable clock frequency range between 10 kHz and 250 kHz, enabling a cutoff frequency up to 25 kHz. It is housed in a 16-pin SOIC package and supports operation within a temperature range of 0°C to +70°C.

Feature Summary

• Integrates an eighth-order elliptic low-pass filter response for high selectivity
• Utilizes switched-capacitor architecture requiring only an external clock signal
• Provides precise analog filtering without requiring external passive components

Applications

• Anti-aliasing filters in data acquisition systems
• Signal conditioning stages for analog-to-digital converters
• Audio processing circuits requiring steep roll-off characteristics

Procurement Notes

Verify component authenticity through authorized distributors or manufacturer channels due to obsolete status. Confirm RoHS compliance and specific suffix designations against official datasheets. Request lot traceability documentation for quality assurance purposes prior to procurement integration.

Selection Notes

Evaluate the required cutoff frequency against the available clock range to ensure proper filter operation. Verify that the system power supply remains within the specified 4.5 V to 12 V limits. Ensure the operating environment stays within the commercial temperature range of 0°C to +70°C for reliable performance.

Part Context

This component belongs to the MAX297 series of active filters, which are designed for applications needing high-order filtering in a compact footprint. The WE+ suffix indicates a lead-free, RoHS-compliant variant packaged in a standard 16-SOIC format suitable for surface-mount assembly processes.
