Introduction :TPA3116D2 digital power amplifier board, with double channel high power, shock volume; The input voltage ranges from DC12 to 28V. DC24V is recommended. Board carrying amplifier chip TLO74C, after input of sound source, first into the amplifier chip for amplification, in the power amplifier chip to make the volume more shocking. Operation :1. Connect the power input terminal to the DC DC power supply of 12V to 28V (24V is recommended). 2. Audio input terminal link audio source, such as MP3, mobile phone, computer, etc. 3. The audio output end is connected to the speaker, pay attention to the positive and negative poles, it is recommended to connect more than 120W professional stage speaker, in order to play its effect. Product features TI's TPA3116D2 is used as the power amplifier chip, with an efficient stereo digital amplifier power pole, which can drive up to 100W/22 speakers in mono mode. Dual channel High efficiency Class D operation: greater than 90% power efficiency and low idle loss A feedback power level architecture with high PSRR reduces PSU requirements Integrated self-protection circuit, including overvoltage, undervoltage, overheat DC, detection and short circuit protection The module uses a large capacity filter capacitor, and the relay protection diode can improve reliability. Product Name: TPA3116D2 Digital Power amplifier board Supply voltage: DC12-26V Output power: 120W*2 Signal to noise ratio: 100db Channel number: two-channel stereo Product size: 92*68*16(mm)

This product is suitable for store solicitation, home video, empty square and other places. Dimensions: 98mmx68mmx16mm. Channel number: two-channel stereo. ? Supply voltage: DC12-26V. TPA3116D2 chip is a digital power amplifier chip with power efficiency of more than 90% and low idle loss, so the heat is very small.
