What are the key features of MAX274ACWI?
- 8th-order continuous-time lowpass filter with up to 150kHz cutoff frequency, implemented without external capacitors for minimal component count
- Pin-selectable Butterworth or Chebyshev filter response enables direct optimization for flat passband or steep roll-off without redesign
- 28-pin SOIC package with single or dual supply operation from 5V to plus or minus 5V rails for analog signal conditioning in mixed-signal systems
What is MAX274ACWI used for?
The MAX274ACWI is used in audio signal processing, anti-aliasing filters ahead of high-speed ADCs, and communications receiver front ends where a high-order continuous-time lowpass characteristic up to 150kHz must be implemented without bulky discrete RC networks. Its pin-configurable filter order and response type make it suitable for instrumentation, data acquisition front ends, and electromagnetic interference suppression in industrial measurement equipment.

Frequently Asked Questions
What filter order and maximum cutoff frequency does the MAX274ACWI provide for anti-aliasing applications?
The MAX274ACWI implements an 8th-order continuous-time active lowpass filter with a maximum cutoff frequency of 150kHz. An 8th-order filter provides 160 dB per decade roll-off beyond the cutoff, which is sufficient to attenuate aliasing components for ADC sampling rates above 300ksps while keeping the anti-aliasing filter design to a single 28-pin SOIC IC.
Why would a designer choose MAX274ACWI over a discrete RC ladder filter for a 100kHz lowpass anti-aliasing application?
A discrete 8th-order RC lowpass filter at 100kHz requires 8 or more precision capacitors and resistors with tight tolerance matching, consuming significant PCB area and assembly complexity. The MAX274ACWI replaces all of these with a single 28-pin SOIC IC that internally defines the filter poles, reducing BOM count by over 10 components, cutting board area, and improving filter accuracy since the on-chip pole frequencies are laser-trimmed to within 1% at the factory.
Can MAX274ACWI be configured for a Chebyshev response instead of Butterworth, and what is the tradeoff?
Yes, the MAX274ACWI supports both Butterworth and Chebyshev filter responses selected via pin configuration. A Chebyshev setting achieves a steeper roll-off beyond 150kHz at the cost of passband ripple of up to 1 dB, whereas the Butterworth mode provides a maximally flat passband with slightly less steep attenuation slope. Engineers select Chebyshev when out-of-band rejection is critical, and Butterworth when flat amplitude response within the passband is more important for the measurement or audio application.
