Maxim Integrated MAX274ACNG+ Programmable Universal Active Filters

The MAX274ACNG+ is a high-performance, programmable universal active filter designed by Maxim Integrated to cater to a wide range of signal processing applications. This versatile filter features four independent second-order filter sections that can be cascaded internally to form higher-order filters such as eighth-order filters. The device provides designers with the flexibility to program the filter to operate in various modes including low-pass, high-pass, band-pass, and notch (band-reject) configurations.

Constructed with precision on-chip resistors and capacitors, the MAX274ACNG+ ensures stable and accurate filter characteristics. The filter cutoff frequencies can be programmed through an external clock or controlled directly via a frequency control voltage. This makes the device extremely adaptable for applications requiring dynamically changing filter characteristics, such as audio processing, signal conditioning, and anti-aliasing for data acquisition systems.

The MAX274ACNG+ operates from a single +5V supply or dual ±5V supplies, which provides additional flexibility in terms of power requirements for different system designs. The device comes in a 24-pin narrow DIP (N-DIP) package, making it easy to integrate into a variety of circuit boards.

Key features of the MAX274ACNG+ include:

• Programmable filter modes: Low-pass, high-pass, band-pass, and notch
• Four independent second-order filter sections
• Internal cascading for up to eighth-order filters
• Programmable frequency range with an external clock or control voltage
• Stable and accurate on-chip resistors and capacitors
• Operates from a single +5V supply or dual ±5V supplies
• 24-pin N-DIP package for easy implementation

Whether you are designing professional audio equipment, sophisticated signal processing systems, or precision instrumentation, the MAX274ACNG+ from Maxim Integrated provides the reliability and performance needed for your filtering requirements. Its programmable nature and high level of integration make it an ideal choice for engineers looking for a flexible and high-quality active filter solution.
