LM2005 20 watt amp circuit
A very simple 20 watt amp circuit electronic project can be designed using the LM2005 dual high power amplifier, designed to deliver optimum performance and reliability for automotive applications. LM2005 20 watt amp circuit has a high current capability (3.5A) that enables the device to deliver 10W/channel into 2ohms (LM2005T-S), or 20W bridged monaural (LM2005T-M) into 4ohms, with low distortion.
Because the LM2005 audio amplifier supports a 4 ohms load into the bridge mode , we recommend to use the following circuit application .
In case that you need a stereo amplifier you can use two circuits ( two separate amplifiers ) each of them connected in bridge mode .
This power amplifier circuit supports a wide input voltage range , between 8 and 18 volts , but because this circuit is designed for automotive applications , the typical power supply required is 14,4 volts DC .
As you can see in the schematic circuit this audio power amplifier will provide 20 watt output power on a 4 ohms load using bridge mode configuration .
