Wiring Diagram Car Mono Amplifier using IC TDA2040

RealAutoTips. - When you need your car completed with good audio sound system, you can build by your self the amplifier for the sound system using simple circuit of Car Mono Amplifier using IC TDA2040 that very easy to build.

In here we will show you the electronic circuit schematic of Car Mono Amplifier using IC TDA2040, and if you need this circuit to be Car Stereo Amplifier using IC TDA2040, you only need to make this circuit double only.

Wiring Diagram

Figure 1. Wiring Diagram Car Mono Amplifier using IC TDA2040 (Circuitstoday)

Component List
  1. R1,R4,R6 = 22K
  2. R2             = 20K
  3. R3             = 680
  4. R5             = 4K7
  5. C1,C5       = 100nF
  6. C2             = 220uF
  7. C3, C4      = 22uF
  8. C6             = 2200uF
  9. C7             = 2.2 uF
  10. IC1            = TDA2040


The main component of Wiring Diagram Car Mono Amplifier using IC TDA2040 is IC TDA2040 as like in figure 1. And we will describe as follow:
  1. IC TDA2040 is a monolithic integrated audio amplifier that operates in Class AB mode. 
  2. The IC has built in circuitry for short circuit protection and thermal shut down and more over it can be operated from a single supply too. 
  3. The amplifier can deliver 12 watts into to a 8 ohm speaker. In the circuit the IC is wired in order to operate from the cars 12V line. 
  4. Capacitor C7 is the input DC decoupling capacitor and R4 provides feedback. Network consisting of resistor R5 and capacitor C5 provides high frequency stability and prevents any chance of oscillation. 
  5. Capacitor C6 couples the ICs output to the speaker. C2 and C1 are power supply filters.
