MAX296EWE

Overview

The MAX296EWE+ is an active switched-capacitor filter manufactured by Analog Devices Inc. under the Maxim Integrated brand. It implements an eighth-order lowpass elliptic response with a cutoff frequency of 25 kHz. The device operates within a supply voltage range of 4.75 V to 11 V and utilizes a 16-pin Wide SOIC package. Key electrical parameters include a propagation delay of 10 µs and a maximum operating temperature of +85 °C. It functions as a full-duplex interface component in signal processing applications, requiring external clocking for operation.

Feature Summary

• Provides high-selectivity eighth-order elliptic lowpass filtering characteristics
• Operates using switched-capacitor technology for precise frequency control
• Designed for single-supply operation within specified voltage limits

Applications

• Signal conditioning in industrial measurement systems
• Anti-aliasing filters in data acquisition circuits
• Audio processing equipment requiring steep roll-off characteristics

Procurement Notes

Verify the specific suffix (e.g., +T) against the required packaging format, as tube and tape-and-reel variants exist. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the design supports the necessary external clock signal requirements inherent to switched-capacitor architectures.

Selection Notes

Select this component when an eighth-order elliptic response is required without discrete passive components. Consider the need for an external clock source, as the filter performance depends on the input clock frequency relative to the cutoff. Evaluate power supply constraints against the 4.75 V to 11 V operational range.

Part Context

This part belongs to the MAX296 series of active filters. It is distinct from the MAX201 or MAX3232 RS-232 transceivers also present in the provided context. The MAX296 family focuses on analog signal filtering rather than digital communication interfacing, utilizing switched-capacitor techniques to emulate inductor-based filter responses.
