Sure Electronics AA-AK32151 2 X 15 Watt 8 Ohm Class D Audio Amplifier DIY Kit
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. If you want to use an AC adapter with 10 to 30 VDC output make sure the DC plug is a 2.1 x 5.5 mm wired tip positive. The 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.
