TPA3116 D2 Is A Class D Power Amplifier IC

Launched by TI, with very high index parameters. The highest modulation frequency can reach 1.2MHZ, and the high-power output distortion is less than 0.1%

50*25*10MM Large Heat Sink

The large heat sink can provide good heat dissipation effect for the continuous high-power output of AMP, thus avoiding the chip from being burned out.

Multiple Power Input Methods

High-grade fence terminal-convenient wiring, not easy to short circuit;Two power input methods can meet your different wiring needs.

Only when the audio input is sufficient and the power supply voltage/current input is sufficient, can there be enough power output.The higher the power supply voltage, the greater the output power;The smaller the impedance of the speaker, the greater the output power. It is recommended to use a 4Ω speaker.Finally, please make sure that the power of the adapted power supply is greater than the actual working power of the AMP to ensure the maximum output power.

Warm Reminder:

The power switch on the board is a standby switch. After the switch is turned off, the machine is in a low-power standby state. To completely turn off the power or unplug it for a long time, you can unplug the DC plug on the machine. Properly increasing the voltage or reducing the speaker impedance can effectively increase the output power.

[Protection Mechanism] The TPA3116D2 devices feature short-circuit and thermal protection as well as overvoltage, undervoltage, and DC protection to prevent total failure. In the event of an overload, the device reports the fault condition to the processor to protect itself from damage.
[High Performance] The TPA3116D2 is a Class D amplifier IC from TI that has very high index parameters. Advanced oscillator / PLL circuit uses multiple switching frequency options to reject AM interference. The modulation frequency can be up to 1.2MHZ, and the high power output distortion is less than 0.1%. This helps prevent noise.
[High Quality] It adopts copper DC connector and fence type terminal. It can withstand large current, no heat, no damage to the wire. Free DC head lead, compatible with the input power interface of this product, even if you dont have a DC head adapter or battery, it can be easily wired.
[Application] With bass, treble and volume control, easy to adjust volume, enjoy the music tone what you want. TDA3116D2 is widely used in store solicitation, home theater, square speakers, etc.due to its excellent performance and comprehensive cost performance.
