回答：The MAX274 and MAX275 are continuous-time active filters consisting of indendent cascadable 2nd-order sections. Each section can implement and all-pole bandpass or lowpass filter response, such as Butterworth, Bessel, Chebyshev, and is programmed by four external resistors. The MAX274/MAX275 provide lower noise that switched-capacitor filters, as well as superior dynamic performance - both due to the continuous-time design. Since continuous-time filters do not require a clock, aliased and clock noise are eliminated with the MAX274/MAX275.The MAX274 comprises of four 2nd-order sections, permitting 8th-order filters to be realized. Center frequencies range up to 150kHZ, and are accurate to within ±1% over the full operating temperature range. Total harmonic distortion (THD) is typically better than -86dB.The MAX275 comprises of two 2nd-order sections, permitting 4th-order filters to be realized. Center frequencies range up to 300kHZ, and are accurate to within ±0.9% over the full operating temperature range. Total harmonic distortion (THD) is typically better than -86dB.Both filters operate from a single +5V supply or from dual ±5V supplies
