MAX274AEWI

MAX274AEWI Description

The MAX274AEWI is an advanced 8th-order active filter IC manufactured by Analog Devices Inc./Maxim Integrated, designed for precision signal conditioning in demanding applications. Housed in a 28-SOIC package, this surface-mount device integrates four continuous low-pass and band-pass filters with a cutoff/center frequency of 150kHz, making it ideal for high-frequency analog signal processing. Operating across a wide supply voltage range (4.74V to 11V single-supply or ±2.37V to ±5.5V dual-supply), it offers flexibility in both industrial and embedded systems. The device is classified under EAR99 and complies with REACH regulations, ensuring global usability.
