Module description:
UAF42 is a universal active filter that can be configured for various low-pass, high-pass, and band-pass filters. 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.

Precautions for using the module:
(1) The power supply of the module is a positive and negative dual power supply, and the voltage cannot exceed 18V.
(2) Since the module is a high-precision device, in order to avoid unnecessary interference, it is recommended to use a linear power supply.
(3) It is recommended to use SMA to BNC line input and output signals for output signals. Use an oscilloscope to observe the effect. Poor contact or poor quality wires may cause signal attenuation or excessive noise.
(4) The filter measurement generally adopts the oscilloscope point frequency method. If possible, you can use a frequency sweeper or a vector network analyzer to test. Please add a DC blocker.
(5) The details in the shop are mainly the introduction of the basic performance of the module and the test chart. If you need the specific working principle and analysis of the circuit, please move to the blog post.
