Don't let the size fool you, the TPA3116 amp board delivers 2 x 50W into 4Ω loads. This device operates from 8V to 26V and provides a high PSRR, eliminating the need for a regulated power supply. The TPA3116 has the ability to be used as a small car amplifier, because it offers up to 90% efficiency at 12 VDC.

Comprehensive click-and-pop reduction circuitry minimizes noise coming into and out of shutdown or mute. Work this amp board into your next small portable speaker project and enjoy the sound without the annoying pop sound when you turn it off.
