Watch George Thomas put this amp together on Ham Nation's "Smoke and Solder" segment.
This Class-D stereo audio amplifier kit incorporates the TPA3122D2 power amplifier IC. Class-D designs provide pristine, accurate audio reproduction combined with an authoritative bass punch, while requiring lower input current than conventional Class-AB amplifiers. Completion of this easy-to-assemble kit will result in a fully functional, dual-channel audio amplifier.
The TPA3122 amp IC is capable of producing up to 15 watts per channel (8 ohms @ 28 VDC input power), and the device's efficiency eliminates the need for an external heat sink when playing music. The complete amplifier can be powered by a wide range of 10 VDC to 30 VDC supplies. Included switch can be used to set the gain as 20 dB, 26 dB, 32 dB, or 36 dB. This kit contains through-hole components exclusively, which solder easily into the pre-drilled printed circuit board. Power supply not included. Dimensions: 121.90 L × 91.40 W × 1.60 H (±0.20) mm.
Note: Please match the components listed in the Users Manual (found in the Manual/Resources section on the right hand side) to the Item Number on the printed circuit board.
Warning: California residents only. Please note per Proposition 65 that this product contains chemicals known to the State of California to cause cancer and birth defects or other reproductive harm.
