2x25W at 4 Ohm TPA3123 Class-D Audio Amplifier Board

This Class-D dual channel amplifier board employs a Tripath-style Texas Instruments TPA3123D2 chip. Each channel is rated at 25W, delivered with state-of-the-art sound quality. The TPA3123D2's efficiency eliminates the need for an external heat sink when playing music under average listening conditions. Integration of high-quality SMD and MKP plug-in capacitors ensures hi-fi amplification output. Requires a DC power supply ranging from +10 to 30V (available separately) and can be used to drive any 4 ohm or 8 ohm passive speakers.

Specifications: • Output power (x 2 channels): 5W @ 8 ohms <0.08% THD+N, 10W @ 8 ohms <10% THD+N; 10W @ 4 ohms <0.08% THD+N, 25W @ 4 ohms <10.0% THD+N • Frequency response: 20 Hz to 20 kHz (±3 dB) • Signal to noise ratio: 100 dB (A-weighted) • Power supply range: 10V to 30V, maximum 32V • Dimensions (mm): 110.2 L x 68.6 W x 16 H.
