SMAKN&reg; TPA3118 numeric 12V power amplifier board finished board /with switch potentiometer /Parallel Mono TPA3118 digital power amplifier board is to use the TI company TPA3118D2 high-performance power amplifier chip, beyond TPA3123 chips.DC power supply, wide working voltage 6-25v power supply, maximum 25W + 25W double sound channel output, support parallel bridge (PBTL) 50W mono output. 1, this board design is practical based, small size (50x50mm), wide operating voltage (6-25V), output power (greater than 25W +25 W stereo), little heat, up to 90% efficiency, sound quality is also nice.2, most of the posts using the high stability SMD chip components, the performance is not comparable to ordinary hand into the material. 3, sealed potentiometer with switch with power LED display, easier to use. 4, with 3.5MM standard audio input jack; 3P socket can be fitted with 4, from "Lin" "G" "Rin" audio input, modification amplifier and more convenient. 5, lower left corner of the board position reserved 5V/150-200mA power "Vout" output connector imports, which can be accessed within the decoding power 5V/180mA (default shipping without a 5V output). 6. Supports parallel bridge (PBTL) 50W mono output, speaker wiring: horn "+" then Lout (+) or (-), the speaker "-" then Rout (+) or (-), the other two pick imports blank.
