Default tda2030a Heatsink

I recently built 2 amps, one using a single tda2030a chip and another using 2 of those chips. I'd like to know if anyone can help me with the size of the heatsink since they heat up A WHOLE LOT when you use them at high volume and i wouldn't like it to blow up. I used the circuits presented in the IC's datasheet.
Thanks in advance guys!

I guess for two chips, one Socket A CPU hetasink (w/o fan) will enough. Because two of them is enough for my 2xLM3886..

use an aluminium enclosure and attach the amp to the enclosure using the heatsink nut ...ensure the back of IC touches enclosure..also add mica sheet between the IC and enclosure...I guess 2030A in not isolated so back must be at -vcc..this should provide adequqte cooling as well as save u the cost of additional heatsinks...

The datasheet gives recommendations on heatsinks suited to use - just buy one with a suitable degreeC/Watt.

It's a pretty low-powered amp, and worse disspation will come c. 1/3rd rated output*. I used to use a pair of LM1875 (25w/ch) on a single 4degC/W heatsink for years without problem.

If the amp is heating up badly without a load, then also check it isn't oscillating - good supply decoupling tight to the IC, a zobel on the speaker output etc....

nono, the amp is heating using it a high volume withan 4ohm speaker. so i guess it's just normal

No such thing as to big of a heatsink the bigger the better

a cpu (slot 1 or something like that) heatsink, without the fan, should be enough and pretty cheap for two 2030's. but given the low price of this heatsinks, i would use one per chip and have them quite cool.
you can find them in "mercado libre" at $5 each.

something like this

If you’re using the circuit from the datasheet it shouldn’t be that hot. U must have problems with the circuit or the insulators must have shorted with the heat sink.

with a 4 ohm load you will definitely have more heat...even a robust amp like 4780 heats up quite a bit driving a 4 ohm load..

I'm using a small heatsink (about 1x2x3 inch) for two TDA2030 without any
problems (doesn't even get warm with medium level output) so I suggest
that you (double) check your circuit (and layout). The 2030 tend to oscillate.

Greetings Till
