MAXIM INTEGRATED / ANALOG DEVICES MAX274BENG Active Filter

The MAX274BENG+ is an 8th order, continuous-time active filter housed in a 24-pin NDIP package. It consists of four 2nd-order sections that can be cascaded to realize complex filter responses. Each section is independently programmable to implement various all-pole filter responses such as Butterworth, Bessel, or Chebyshev, by adjusting four external resistors. This filter offers lower noise and superior dynamic performance compared to switched-capacitor filters, as it does not require a clock, thereby eliminating clock noise. Typical applications include audio, sonar, and avionics frequency filtering, DAC output smoothing, low-distortion anti-aliasing filters, modems, and vibration analysis. Key specifications include a supply voltage range of 2.37V to 5.5V, a temperature range from -40°C to 85°C, center frequencies up to 150 kHz with ±1% accuracy over temperature, a total harmonic distortion of approximately -86 dB, a supply current of 20 mA, and a slew rate of 10 V/µs.
