TDA7384 - 4 x 22W car power amplifier
If connect to car battery where operating voltage is about 13.2V, then each channel can give 22W(4Ω) – what is more than enough for me. This amplifier I probably will use to test audio processor TDA7313 which is stil in development phase.
I didn’t find much information about this chip on the internet so I decided to built it and try on my own. As datasheets of TDA7384 says it is low distortion, low output noise, low external component count. Also has Stand-By function and Mute function. It has several protections like from output short circuit to GND or to Vs, capable to handle very inductive loads, thermal limiter, load dump voltage. TDA7384 is an AB power amplifier cased in flexiwatt25 (eagle library is included in project archive) package wich is designed for high end car radio applications. It allows rail to rail output voltage swing with no need of boot-strap capacitors.
 |
| Schematics TDA7384 |
I have followed the schematic in datasheed when building circuit. In datasheet you may also find PCB layout but it is two layered and didn’t fit to may box I’ve chosen. So I have made single sided PCB 50X100mm.
![]() |
| PCB TDA7384 amplifier |
As I put pins on PCB for ST-BY and Mute but I not using them, I connected these pins to VCC like it is shown in PCB view. According to datasheet St-By and Mute turns off amplifier if signal in input is lower than 3.5V. So it is recommended to connect these pins to Vcc if not used.
Maximum power dissipation of chip is 80W(Tcase=70ºC), so it can handle 4 channels working at power of 20W each. But of course chip in a box doesn’t have good ventilation so I’ve put a radiator to ensure that amplifier effectively dissipates heats. I didn’t try to load amplifier to maximum to se if it doesn’t heat up to much. But at normal sound level it stays warm what is normal.

| On box amplifier |
Dont forget to put thermal paste between chip and radiator to ensure lower thermal resistance. And here we go – brand new power amplifier ready to go:

20 Watts Power Amplifier circuit can be made with an IC power amplifier LM1875. IC LM1875 is a single chip power amplifier from National. 20 watts audio amplifier with LM1875 is a low power amplifier with good quality to the room.
To assemble the amplifier 20 watts with IC LM1875 component is not needed much support. 20 watts power amplifier using LM1875 IC in this article using symmetrical power supply. The series of 20 watts audio power amplifier with IC LM1875 can be used as an experiment or first project for the reader, because it is simple and assembly of high success.

| Schematic Amplifier LM1875 |
LM1875 amplifier circuit with the above may result in the strengthening of the voltage up to 27dB for each channel (1 channel 1 IC). Strengthening the voltage can be changed by changing the feedback that is R5 R (on the circuit above using R 22K). But the tension reinforcement can not be less than 20 dB because it can cause oscillation. For the power supply or power supply 20 watts power amplifier rngakaian with lm1875 can use travo 2-3A with CT.
