LM 3886 bridged
 

Does someone have a pcb(or at least a schematic) for 2LM 3886 bridged?Something simple not too complicated

LM3886 bridged??
 

What are you looking for exactly? Are you looking to invert at the chip or use a buffer like a DRV134 for the bridge, what voltage supply ect... theres alot of circuits out there, whats the load your going to be driveing ect......

NEVER drive loads bellow 8 Ohms with 3886 bridged ! :hot:

8 ohms
 

Ive driven loads as low as 3ohms bridged without an issue, just take a lot of thermal and current control work.

First,10x for the replyes.I want to invert the signal at one chip(as in the app notes),the load will be 5,7ohm,the supply voltage is not an issue(i`ll have one ordered as i need,i think +/-30V would be good enough-correct me if i`m wrong).

Nobody,not even a schemattic?

OK How abot this one:

100 watss into 8 or 4 ohms depending on power supply voltages.

I think it should deliver 140 W RMS into 8 ohms with proper supply voltages and large heatsink. I usually use a large aluminium sheet , at least 5 mm thick, it works well.

I was hoping to get about 120W into 8ohms with +/-30V.
Is it realy that necessary to have a 8ohm load?I`ll probably have a 6 ohm load
