"nominal" 4 ohm load ?
Under the "Recommended Operating Conditions" (sec 6.3 of the datasheet), it makes mention of a 3.2 ohm minimum load (BTL, 10uh & 680nf filter).
Does anyone have any feedback with running a "nominal" 4 ohm load with this amp ? (YJ BB).
Just asking in efforts to avoid the amplifier going kaput or at worse, damaging speakers.

This means the amp won't be stable below 3.2 ohm, you can use higher impedance anytime.
Breeze Audio Mono TPA3116 at aliexpress
Hi all,
Does anyone have any experience with these Breeze Audio TPA3116 mono amps from Aliexpress?
breeze audio TPA3116 100w 1.0 mono digital audio power amplifier ,Sound good than expected aluminum mini amplifiers hot SALE-in Amplifier from Consumer Electronics on Aliexpress.com | Alibaba Group
Looking at the back image it has two phono inputs, has anyone ever seen this on a "mono" amp?
Cheers,

YJ BB is negative exception (see YouTube), any other is surprisingly stable even into 1 to 2 ohm loads.
Hi Irribeo,
Are those boards in PBTL config ?
I've seen a strongly negative youtube review where the board was overloaded into a 4 ohm load with a 26v input. To the best of my understanding, the chip supports 2 x 50W @ 21v (4 ohm).

YJ BB drives 2x2w @16V PSU into 4 ohm zobelled speakers with bad result, any other amp is better.
Yes any YJ BB is faulty as in uncomparable with any decent amp, even at my listening level, that shouldn't be too hard and is easy enough for even STM's and tpa3110 on same speakers.
Just got one of these.
DC 12V-24V TPA3116 Mono Channel Digital Power Audio Amplifier Board BTL Max 100W | eBay
R1 is 01D which would be 100K
and R2 is 473 which would be 47k?
How is this even possible?
Nearest I can find in the TI datasheet is in slave with R1 100k and R2 39k.
Edit : I want to lower the gain, since it is very high. Already with my TV at 1 its loud, and even at 0 theres hissing.

I got one of those boards and saw the resistors wrong. I changed them to 100k and 39k which would put it in Master mode.
Unfortunately my board was defective from the start. I thought maybe the resistors were causing the strange oscillation I was seeing on the scope. But no such luck. The board completely died after 30 minutes.
I opened a separate post about the board a week or so ago. If you look, you will find it.

I bought the red dual chip board and the right channel didn't work.
2X100W TPA3116 D2 Dual Channel Digital Audio Amplifier Board 12V 24V for Arduino | eBay
There is a faint click upon turn on and the left channel does that but there's nothing on the right. I tried switching speakers and it's the same. If it is bad connector, most likely the right channel would be noisy or something like that. But this is nothing at all. Could it be the pot, female 3.5mm socket, or the chip itself?

If you purchased it from a EB vendor, just return it instead of spending time trying to figure out what's wrong. One can spend a lot of time without getting anywhere. My 2 cents.

Probably true. I messaged him soon after I found out and will not do anything permanent to change it. I was curious if this is a known issue with this board but it seems not to be the case. Is that the recommended board for 3116? Thanks fellas.
Smallest / Worst TPA3116 board
I ordered one of these tiny TPA3116 boards for ~$4.50 and it arrived today.
I didn't have high expectations, but I thought it might be good for playing with different input and output filter arrangements. Now that I have it and I'm looking at it closely, I'm starting to doubt it will be good for anything. I'll probably play with it a bit at some point though.

Interesting. Have not seen this one before. Did not see the usual output LC filter. Probably use a ferrite bead??
On my 2.1 TPA3116, I pushing a maximum of 70+w at ~25.6v into a 4 ohm woofer on the PTBL sub channel. Has worked at high volume for many hours now. If I had to, I could do this on a single channel and not use the other.
The max rating for each single channel at 50w (total 100w both channels driven) is the TPA3116's thermal dissipation limit.
I like this board. I've had two and both worked as advertised. It's a little light on the very low end bass because of a filter cap (easily modified). I've reverse engineered the sub's fixed2nd order low pass filter (stock: butterworth @107hz). I modified the filters F0 and Q by replacing two thru-hole poly box caps.
