MAX296CSA+

Overview

The MAX296CSA+ is an 8th-order, lowpass, switched-capacitor filter in the MAX291 series. It provides a Bessel response characterized by low overshoot and fast settling times. The device operates with a clock-to-corner frequency ratio of 50:1, supporting corner frequencies from 0.1Hz to 50kHz. It requires no external resistors or capacitors for filter configuration and can utilize either an internal oscillator or an external clock signal. The component functions on single +5V or dual ±5V supplies and includes an uncommitted operational amplifier.

Feature Summary

• Bessel filter response optimized for preserving step input shapes and achieving rapid settling
• Integrated internal oscillator or provision for external clock signals
• Uncommitted operational amplifier available for anti-aliasing or clock-noise filtering

Applications

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

Procurement Notes

Verify the specific suffix 'CSA+' against the manufacturer's current ordering information to confirm package type and RoHS compliance status. Ensure the required operating temperature range aligns with the commercial grade specifications defined for this part number variant before finalizing procurement.

Selection Notes

Select the MAX296CSA+ when a Bessel response is required for applications demanding minimal overshoot and fast settling characteristics. Verify that the system clock frequency allows for the desired corner frequency within the specified 50:1 ratio. Confirm that the supply voltage requirements match the single or dual supply capabilities of the device.

Part Context

This component belongs to the MAX291/MAX292/MAX295/MAX296 family of 8th-order lowpass switched-capacitor filters. While other variants offer Butterworth responses or different maximum corner frequencies, the MAX296 specifically delivers Bessel characteristics suitable for multiplexer-driven data acquisition systems requiring quick channel settling.
