MAX7490CEE

Overview

The MAX7490CEE is a dual universal switched-capacitor filter manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates on a single 5 V supply with a voltage range of 4.5 V to 5.5 V. The device features two independent channels, each capable of realizing various filter functions including low-pass, high-pass, bandpass, and notch configurations. It supports a cutoff frequency up to 40 kHz and is housed in a 16-pin QSOP package. The component is rated for commercial operating temperatures between 0°C and +70°C.

Feature Summary

• Dual-channel architecture providing independent signal processing paths within a single integrated circuit
• Universal switched-capacitor topology enabling flexible configuration of multiple standard filter responses
• Single-supply operation compatible with standard 5 V logic and power systems

Applications

• Audio signal conditioning and equalization circuits
• Instrumentation front-end filtering
• Data acquisition system anti-aliasing filters

Procurement Notes

Verify the specific suffix CEE against the official datasheet to confirm package type and temperature grade. Confirm RoHS compliance status through the manufacturer's current documentation. Check for obsolescence notices or lifecycle changes directly from Analog Devices before finalizing procurement plans.

Selection Notes

Select this component when dual-channel filtering is required without external op-amps. Ensure the clock frequency requirements align with the switched-capacitor nature of the filter. Verify that the 40 kHz bandwidth meets the application needs. Compare pin compatibility if replacing older versions within the MAX7490 family.

Part Context

This part belongs to the MAX7490 series of dual universal switched-capacitor filters. It shares functional similarities with the MAX7491 but differs in supply voltage specifications. The series is designed for applications requiring precise analog filtering in digital environments.

Replacement Considerations

The MAX7490EEE is a related variant within the same family. Verify electrical parameters and package compatibility before substitution.
