low pass filter subwoofer by TL072

The Acoustic transmute a filter found in many points in the sound Knownest the applications they are baxandal filters for bass and high frequency control and filter the crossover Acoustic transfigure space is separated in the subareas in order to take the match. loudspeakers. Applications that we offer you a simple filter that limits the area of Acoustic transmute region (20-20000Hz) in the region 20-100Hz.

Buffer Opamps by CA3140

The buffer electronic with IC Opamps by CA3140 (More circuits use CA3140) or LF353 or TL072.
If output impedance of a point is a high value then connecting another circuit at that point will load it resulting in malfunction or error. Buffers are used as interface between circuits. Low impedance of an output means it can source sink lot of current, when you need 2 opamps use LF353 (More circuits use LF353)or TL072 which are dual opamps. A non-inv FET input is the best buffer, for inverting buffer use high R values Using very high R values like 2.2M or higher requires a glass epoxy PCB and guard rings around pin 2, 3 to prevent leakage currents on the PCB reaching the PINs. Also moisture and dust has to be prevented by using RTV coating or Varnish. Use 78L05 79L05 for the dual supply required by this circuit.

12V to 50V dc converter for car by TL072 + 2N3055

I used a main part and 2N3055 Transister and IC TL072 for pulse oscillator generator.
The output have voltage +50V and -50V at 2A to 3A.
You must is used this circuit for audio sound automotive or motorcycle amplifier.
