It uses a classic state-variable analog architecture with an inverting amplifier and two integrators. The integrator includes an on-chip 1000pF capacitor trimmed to 0.5%. Many filter types can be easily implemented, such as Butterworth, Bessel and Chebyshev. A fourth useless FET input operational amplifier (same as the other three) can be used to form additional stages, or for special filters such as band stop and inverse Chebyshev. Generally used in power system, sensor signal processing, transmitter and receiver, signal generator processing, etc.\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e \u003c\/div\u003e\n\u003cdiv\u003e \u003c\/div\u003e\n\u003cdiv\u003e \u003c\/div\u003e\n\u003cdiv\u003e\u003cimg src=\"https:\/\/ae01.alicdn.com\/kf\/S6cddb67a50fa48eb92348fcedc43a8927.jpg\" slate-data-type=\"image\"\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cimg src=\"https:\/\/ae01.alicdn.com\/kf\/H6ba035c4b14b40758e5d5a6ee606d497a.jpg\" slate-data-type=\"image\"\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan style=\"font-size:28px\"\u003ePrecautions for using the module\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e \u003c\/div\u003e\n\u003cdiv\u003e \u003c\/div\u003e\n\u003cdiv\u003e \u003c\/div\u003e\n\u003cdiv\u003e \u003c\/div\u003e\n\u003cdiv\u003e\n\u003cdiv style=\"font-size:13.3333px\"\u003e\u003cspan style=\"font-size:18px\"\u003e(1) The power supply of the module is a positive and negative dual power supply, and the voltage cannot exceed 18V.\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv style=\"font-size:13.3333px\"\u003e\u003c\/div\u003e\n\u003cdiv style=\"font-size:13.3333px\"\u003e\u003cspan style=\"font-size:18px\"\u003e(2) Since the module is a high-precision device, in order to avoid unnecessary interference, it is recommended to use a linear power supply.\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv style=\"font-size:13.3333px\"\u003e\u003c\/div\u003e\n\u003cdiv style=\"font-size:13.3333px\"\u003e\u003cspan style=\"font-size:18px\"\u003e(3) It is recommended to use SMA to BNC line input and output signals for output signals.
