Overview
Welcome to use this 2*25W amplifier board from Sure Electronics. Sure has developed
many Class-D amplifiers such as 0.5W, 2W, 8W, 15W, 50W, 100W and one-channel,
dual-channel, four-channel amplifiers to meet different requirements of customers. As a
new member of class-D amplifier series, this 2*25W amplifier board employs TPA3123D2
chip from TI. It supports dual channel amplification and each such channel is rated at 25W
which helps producing state-of-the-art sound quality. The efficiency of the TPA3123D2
eliminates the need for an external heat sink when playing music. Besides, integrating
high-quality SMD and MKP plug-in capacitors ensures Hi-Fi amplification output.
This amplifier can readily be powered by any DC power supply ranging from +10 to 30V.
You can use it to drive any 4
Ω
or 8
Ω
passive speakers. It’s an ideal choice for electronic
hobbyists and audio enthusiasts.
