MAX296CWE

Overview

The MAX296CWE is an active filter integrated circuit manufactured by Analog Devices Inc./Maxim Integrated. It implements a single Bessel low-pass switched-capacitor filter with an eighth-order response. The device operates within a supply voltage range of 1.2 V to 1.8 V and features adjustable overvoltage thresholds. It includes a watchdog timer, power-fail detection, and a reset delay time of 50 ms. The unit draws a working supply current of 300 uA and dissipates up to 600 mW. It is housed in a 16-pin SOIC-Wide package and functions within a commercial temperature range of 0°C to +70°C.

Feature Summary

• Provides an eighth-order Bessel low-pass filter response using switched-capacitor technology.
• Integrates comprehensive microprocessor supervisory functions including watchdog timer and power-fail detection.
• Features adjustable overvoltage thresholds and configurable active high/low push-pull outputs.

Applications

• Microprocessor system monitoring and supervision
• Signal conditioning for low-frequency analog data paths
• Noise filtering in embedded control circuits

Procurement Notes

Verify the specific suffix designation against the manufacturer's official documentation to confirm exact electrical characteristics and package variations. Ensure that the selected variant matches the required operating temperature range and supply voltage specifications for the target application environment before finalizing procurement orders.

Selection Notes

Select this component when a combined solution for signal filtering and system supervision is required. The integrated nature reduces board space compared to discrete implementations. Verify compatibility with the system's clock frequency requirements for the switched-capacitor filter operation and ensure the supply voltage aligns with the specified 1.2 V to 1.8 V operational window.

Part Context

This part belongs to the MAX296 series of active filters produced by Maxim Integrated, now part of Analog Devices. The series focuses on providing precise analog filtering capabilities alongside digital interface support. The MAX296CWE specifically denotes the commercial temperature grade version packaged in a wide SOIC format, designed for general-purpose electronic applications requiring stable filter performance.

Replacement Considerations

Consult official cross-reference lists for verified substitutes such as the MAX296EWE for extended temperature ranges. Confirm pinout compatibility and functional equivalence before replacing the component to avoid circuit redesign requirements.
