Subwoofer amplifier – The single ic can produce only the maximum power of 20 watts. in this case, we are bridging two ic and get a maximum power output of 40 watts. it’s good for working a subwoofer with a fine sound. In this, I am going to discuss details about how to make a power amplifier for your subwoofer.
check what is mean by Subwoofer here. the subwoofer amplifier which works on low-frequency range.
To work the subwoofer we need a powerful amplifier. These days a budget based subwoofer board is a bridge-type Tda2030 ic amplifier. in bridge condition, the ic will produce a Maximum of 40 watts output.
Tda2030 Pinout of TDA 2030
The tda2030 contains 5 pins. and this ic is very easy to use because of fewer connections needed for producing the HI-Fi amplifier.
| Pin Number | Pin name | Description |
| 1 | Non inverting input | Non inverting input (+) of the amplifier |
| 2 | Inverting input | Inverting input (-) of the amplifier |
| 3 | Gnd | connect to the ground connection |
| 4 | Output | This is the output to the speaker |
| 5 | vs | positive voltage supply |
Features
- Low-frequency class AB power amplifier and it will suitable for all types of amplifier.
- Single ic can produce up to 20 watts.
- Wide range of power supply from 6v to 35v.
- short circuit and thermal protection available.
TDA2030 equivalent ic
TDA 2050 is the equivalent to the TDA2030 and TDa2030A IC. The pinout is same but the output power is different, so the comparing the performance the TDA2050 is the best IC.
The TDA 2030 integrated circuit is the best choice to make good audio amplifier circuits. It is used to make mini amplifier outputs from 10 watts to 200 watts.
And a lot of types of mono or stereo OTL, OCL, BCL. Example of a super bridge amplifier of 200 watts details are given in the video
The main advantage of the bridge type amplifier that it will give more power output. Ashish supporting of TDA 2030 in bridge-type amplifier adding for transistors that will boost up the power output.
Using 12-0-12 7 ampere transformer will give 140 watts. And the maximum output of 200 watts we will get.
this is not dual power supply circuit it only single supply circuit designed for car amplifier
yes you are correct contains low pass filter and the filtering range in between 40-150 hz
