MAX7491EEE+ Description
MAX7491EEE+ Description
The MAX7491EEE+ from Analog Devices Inc./Maxim Integrated is a high-performance 2nd-order universal switched-capacitor filter designed for precision signal conditioning in low-voltage applications. Housed in a compact 16-QSOP surface-mount package, it operates within a 2.7V to 3.6V supply range, making it ideal for portable and battery-powered systems. With a 40kHz cutoff/center frequency, this dual-filter IC (two independent filters per device) offers exceptional flexibility for anti-aliasing, noise reduction, and frequency shaping. Compliant with ROHS3 and REACH standards, it features MSL 1 (Unlimited) moisture sensitivity, ensuring reliability in harsh environments.
MAX7491EEE+ Features
- Universal Switched-Capacitor Architecture: Programmable as low-pass, high-pass, band-pass, or notch filters.
- Dual Independent Filters: Integrates two 2nd-order filters in one IC, reducing board space and BOM cost.
- Low-Voltage Operation (2.7V–3.6V): Optimized for battery-powered and portable electronics.
- 40kHz Frequency Range: Suitable for audio, instrumentation, and communication systems.
- Surface-Mount (QSOP-16): Compact footprint for space-constrained designs.
- Robust Compliance: ROHS3, REACH Unaffected, and EAR99 (export-friendly).
MAX7491EEE+ Applications
- Portable Medical Devices: ECG/EEG signal conditioning with minimal power draw.
- Industrial Sensors: Anti-aliasing for ADC front-ends in data acquisition systems.
- Audio Processing: Noise filtering in headsets and microphones.
- Wireless Communication: Baseband filtering in low-power RF modules.
- Test & Measurement Equipment: Tunable filter stages for signal analysis.
Conclusion of MAX7491EEE+
The MAX7491EEE+ stands out for its versatility, low-power operation, and dual-filter integration, offering a cost-effective solution for precision analog filtering. Its 40kHz range and universal configurability make it superior to fixed-topology filters, while the QSOP-16 package ensures compatibility with modern SMT assembly. Ideal for medical, industrial, and consumer electronics, this IC combines performance with efficiency, meeting stringent environmental and regulatory standards.
