3 Watt power amplifier schematic


This time I will share a circuit of schematis power amplifier with LM380 IC that has similarities with LM384. Enough with just a few components you have to make this power amplifier circuit . All components with relatively low prices and making a fairly easy. For this amplifier output power has 3W with 4 ohm impedance. Indeed , this amplifier has the output is quite low and certainly will not be maximal if it works on the speakers with high power.

Making an RIAA phono preamp

Before we start today's blog post, I think I really need to clarify what we’re discussing. I’ve recently got back into vinyl in a big way. Part of the reason for this is the fantastic “Vinyl Decision” in Taipei, run by a couple of very fine gentlemen by the names of Mark and Terry ( https://www.facebook.com/VinylDecision / http://www.vinyldecision.com/ ). If you're in Taipei, and like music, pay them a visit. A recent purchase from there brought back memories of trying again, and again (and again) to play guitar like my guitar heroes as a teenager in the 1980s. In fact, vinyl is making quite a comeback worldwide. A lot of people are realizing that digital versions just lack some of the personality that vinyl can provide. Many of them are buying old record players/turntables and wiring them up to their modern amps. However, they are often disappointed to find that the output audio is very quiet and lacking bass. This is because records are/were recorded using a very specific f...

5 1 surround amplifier circuit schematic

Image
This 5.1 surround amplifier circuit schematic use the IC AN7168 as the main component from this circuit . Minimum voltage required 12V and maximum voltage 24V , I recomended it 12 V because the voltage support on are components. But if you want to better a loud sound you can raise it.  Maximum power output 40W with impedance 4 ohm . This 5.1 surround amplifier circuit schematic also support to make surround sound or 5.1 speaker. Use this amplifier on rear speaker , left right , and center but dont use to subwoofer speaker. See 5.1 surround amplifier circuit schematic below : Click to view large If you want to make a 5.1 surround sound you must make 5 the circuit of 5.1 surround amplifier circuit schematic , for left and right speaker , rear left and right speaker , and center speaker. Use the subwoofer speaker with support amlplifier subwoofer circuit .

DC motor driver with H Bridge IC L293D

Image
Making a DC motor driver with H-Bridge technique can use IC L293D as in the article "DC Motor Driver H-Bridge L293 (2 Motor DC)"is. DC motor driver L293D can be used to control the DC motor 2 pieces at once. DC Motor Driver L293D can be used to control a DC motor continuously or with a PWM technique. Dc motor driver circuit in the article "DC Motor Driver H-Bridge L293 (2 Motor DC)" only use IC L293D only. For more details see the following figure. Working system of DC motor driver L293D is to provide control signals in the form of logic or pulse to the input lines 1A - 1B for DC motor control M1 and the input 2A - 2B for the control of DC motor M2 with the following conditions: Input A Input B Motor DC 0 0 Motor silent 1 0 motor rotates counterclockwise 0 1 Motor berputer clockwise 1 1 Motor silent Description: Enable Input given a logic 1 to obtain such data in the table above.
