MAX296CWE+

Overview

The MAX296CWE+ is an 8th-order, lowpass, switched-capacitor filter from the MAX291 series. It features a Bessel response for low overshoot and fast settling. The corner frequency is tunable from 0.1Hz to 50kHz using a clock-to-corner-frequency ratio of 50:1. It operates on a single +5V supply or dual ±5V supplies. An uncommitted op amp is included for post-filtering or anti-aliasing.

Feature Summary

• Bessel filter response providing low overshoot and fast settling times
• Clock-tunable corner frequency range from 0.1Hz to 50kHz
• Internal oscillator or external clock input capability
• Integrated uncommitted operational amplifier

Applications

• ADC Anti-Aliasing Filter
• DAC Post-Filtering
• Noise Analysis

Procurement Notes

Verify the specific suffix 'CWE+' against the manufacturer's current datasheet to confirm package type (16-pin Wide SO) and temperature range (0°C to +70°C). Confirm RoHS compliance status as indicated by the '+' suffix in official documentation before finalizing procurement specifications.

Selection Notes

Select the MAX296CWE+ when a Bessel response with fast settling is required for multiplexed signal paths. Ensure the application requires a maximum corner frequency up to 50kHz. Verify that the system can provide a stable clock signal within the recommended frequency range to maintain accurate filter characteristics.

Part Context

This component belongs to the MAX291/MAX292/MAX295/MAX296 family of 8th-order lowpass switched-capacitor filters. The MAX296 variant specifically provides a Bessel response, distinguishing it from the Butterworth response of the MAX291/MAX295. It shares the same pinout and general architecture but offers a higher maximum corner frequency compared to the MAX291/MAX292.

Replacement Considerations

The MAX296EWE+ serves as the industrial temperature grade (-40°C to +85°C) replacement for the commercial grade MAX296CWE+. Both share identical electrical characteristics and pin configurations.
