MAX294CWE

Overview

The MAX294CWE is an 8th-order, lowpass, switched-capacitor filter from the MAX291 series manufactured by Analog Devices Inc./Maxim Integrated. It is housed in a 16-pin Wide SO package and operates within a temperature range of 0°C to +70°C. The device provides a fixed Butterworth response with a clock-to-corner frequency ratio of 100:1, supporting corner frequencies from 0.1Hz to 25kHz. It requires no external resistors or capacitors for filter configuration and can utilize either an internal oscillator or an external clock signal.

Feature Summary

• Provides an 8th-order lowpass Butterworth filter response for maximally flat passband performance
• Operates using an internal oscillator or an external clock signal without requiring external resistors or capacitors
• Includes an uncommitted operational amplifier suitable for anti-aliasing or clock-noise filtering applications

Applications

• ADC Anti-Aliasing Filter
• DAC Post-Filtering
• Noise Analysis
• 50Hz/60Hz Line-Noise Filtering

Procurement Notes

Verify the exact part number against official manufacturer documentation before procurement. Confirm that the ordering suffix corresponds to the required package type and temperature rating. Ensure compatibility with existing system voltage supplies and clock requirements. Check for any specific handling instructions related to the component's manufacturing status.

Selection Notes

Select this component when a fixed 8th-order lowpass Butterworth response is required. Verify that the desired corner frequency falls within the supported range of 0.1Hz to 25kHz. Ensure the system can provide the necessary clock frequency, which must be at least 100 times the target corner frequency. Confirm that the 16-pin Wide SO package fits the available board space.

Part Context

This component belongs to the MAX291 series of 8th-order, lowpass, switched-capacitor filters. The series includes variants with different filter responses and frequency ranges, such as the MAX291, MAX292, MAX295, and MAX296. These devices are designed to deliver high-performance filtering in a compact footprint with minimal external components.
