MAX274

The MAX274 are continuous-time active filters comsisting of independent cascadable 2nd-order sections. Each section can implement any all-pole bandpass or low pass filter response, such as butter-worth, bessel, and chebyshev, and is programmed by four external resisters. The features of MAX274 are as follows: (1)continuous-time active filters-no clock, no clock noise; (2)implement butter-worth, bessel, chebyshev and pther filter responses; (3)lowpass, bandpass outputs; (4)operate from a single +5V supply or dual ±5V supply or dual ±5V supplies; (5)design software available; (7)MAX274 evaluation kit available; (8)8th-order-four 2nd-order sections.

The absolute maximum ratings of the MAX274 are: (1)24-pin narrow plasic DIP(derate 13.33mW/ above +70): 1067mW; (2)28-pin wide SO(derate 12.50mW/ above +70); (3)24-pin CERDIP(derate 12.50mW/ above +70): 1000mW; (4)operating temperature ranges: 0 to +70; (5)storage temperaturerange: -65 to +165; (6)lead temperature(soldering 10sec).

The following is about the electrical characteristics of MAX274: (1)maximum operating frequency: 10MHz; (2)center-frequency range: 100 to 150kHz; (3)center-frequency accuracy: -1.0% min and 1.0% max; (4)Q accuracy-unadjusted: -10% min and 10%; (5)Q accuracy-adjusted: ±2.8% at scaled for bandwidth compensation; (6)temperature coefficient: -28ppm/; (7)Q temperature coefficient: 160ppm/; (8)widerband noise: 23VRMS at 1Hz to 10Hz.
