2x8W at 4 Ohm TPA3110 Class-D Audio Amplifier Board

Each channel of this Class D dual channel amplifier board is rated at 8 watts, delivered with state-of-the-art sound quality. The TPA3110's efficiency eliminates the need for an external heat sink when playing music under average listening conditions. Integration of high-quality SMD and MKP plug-in capacitors ensures hi-fi amplification output. Requires a DC power supply ranging from 10 to 16V (available separately) and performs admirably with 4 ohm and 8 ohm speakers.

Specifications: • Output power: 3W x 2 @ 8 ohms (<0.1% THD+N), 5W x 2 @ 8 ohms (<10% THD+N), 6W x 2 @ 4 ohms (<0.1% THD+N), 8W x 2 @ 4 ohms (<10.0% THD+N) • Frequency response: 20 Hz to 20 kHz (±3 dB) • Signal to noise ratio: 100 dB (A-weighted) • Recommended power supply: 10 to 16 VDC • 2.1 mm DC input jack • Dimensions (mm): 98.48 L x 52.90 W x 16.10 H.

2x8W at 4 Ohm TPA3110 Class-D Audio Amplifier Board
2x8W at 4 Ohm TPA3110 Class-D Audio Amplifier Board is rated 4.8824 out of 5 by 17.
Rated 5 out of 5 by from Works like a charmI bought these to mate with some small desktop full range 3 inch Fountek speakers that were on sale here. I built some small cubes for the Fountek's and then attached this little board to the underside of one of the cubes. Connected the amp to a 12v 5 amp power supply and then connected my tablet with a 3.5mm plug and the speakers. It sounds great. This small board works great as a near field device. I would not recommend this is you want to fill a large room with sound, but for sitting at a desk and listening to voice or background music this works like a charm.This is a good value and the sound is very clear. I ordered two more for future projects.

Rated 4 out of 5 by from Excellent amp!I bought this amp a couple weeks ago just to experiment with. The amp has decent volume from most sources. What I like most about the amp is the clarity and excellent stereo image. The only thing is the amp could have more input sensitivity and volume, and better bass response. But good clean amp will work great with most projects, Just make sure input has decent voltage level.

Rated 5 out of 5 by from You have to hear it to believe it!I've built a half dozen or so portable powered speaker systems using a few of the various 2x15 watt board amps available from various sources. Having to always pad the input signal to not overpower the drivers, I thought I'd try this 2x8 watt board. I figured I'd be trading away some sound quality but, lo and behold, I find this may actually be a step up -- and still requires a pot on the input for the smaller systems. In fact, I am going to try the Sure 2x2 watt amp, next, for these.To fully test the capability of this amp's 2x8 watts, I am currently listening to it through a pair of Optimus PRO LX-8s I am in the middle of reengineering. This amp delivers the goods, even with crossovers less efficient than the originals for these love/hate speakers. Here's what is so surprising -- I am comparing this amp to my "bench" amp used in this setting, a Stewart Audio World 1.2, which produces a nicely clean 2x300 watts at 4 ohms. This is what I am hearing: the Stewart with input controls at half matches this Sure at full; this Sure presents slightly better detail and stereo separation from about 2k on up; the Stewart is better at controlling bass, but the bass from this Sure still sounds rather good. In short, I am nearly giggling because of what this little board can do as I blast iTunes Radio's Latin Jazz station through it.Other things I very much appreciate include easy hookup via onboard jacks for power, audio input, and speaker output; input voltage requirements that accommodate eight NiMH AAs; and, best of all, holes for mounting!

Rated 5 out of 5 by from Great little ampBought this to power two speakers on my computer, works great

Rated 5 out of 5 by from Superb Tripath SoundJust hooked this up to my home stereo. I have a number of Tripath based amps that use the TA2020, TA2021 and TA2024 chips. I've also got an amp that uses the newer TPA3116. To my ear this sounds as good as any of them. Since it (obviously) lacks a volume control, I hooked it up to an Bravo Audio Ocean Preamp and it is a match nearly made in heaven. Even though this is only an 8 watt amp, the Bravo Audio Ocean has so much gain that you'll be shocked how loud you can drive your speakers. My only complaint is that I can only use about the first 1/10th of the travel in the Bravo's volume knob before it gets too loud with my 92db Axiom M3 speakers.

Rated 5 out of 5 by from Wonderful little thingBought this little guy, because I wanted a TPA3116 but didnt want to wait for an order from China. And Im glad I did. I love this Amp. I currently have it installed with a rat shack pot in an old wooden .22lr ammo box. Using a pair of Boston HD5s, the sound is stellar.

2x8W at 4 Ohm TPA3110 Class-D Audio Amplifier Board

what is J8 for? where can i connect a pot for gain control? thanks

Asked by: anef88

The PE description says the power supply can be a maximum of 16 volts while the Sure users manual states a maximum of 19 volts.  Which is correct?  If the Sure manual is correct, would a 19.5 volt supply be safe to use?

Asked by: JefffromMN

I'm thinking of a project using this board and I may want to throw a 4 ohm speaker on one channel and an 8 ohm on the other. Is that a terrible idea, or will that work out?

Asked by: JohnnyHN
There is nothing wrong with doing this on this amplifier.

Are the J1,J2 sockets for input (same as the 3.5mm jack on PCB)? If so, which is L/R? Same with Output, which channel is Ch 1/2 (L,R)? I'm planning on using sig input directly from a USB bluetooth receiver, powered by a step-down DC regulator (12v to 5v).

Asked by: TIM 7
Yes, J1 and J2 are the inputs. J1 is Left and J2 is Right. J3 is Left output and J4 is Right output.

What is the idle current rating of this amp?

Asked by: tecsplus
Sorry about that. Downloaded the user manual and it is 20ma with a 12VDC supply. Very good for battery operation.
