USB Powered Small Amplifier 5V AC/DC PM CM2038 Amplifier Board 5Wx2 Hi-Fi Finished Board
OVERVIEW
The PM2038 is a dual BTL audio power amplifier. The PM2038 can provide 3.5W output power (5W peak) to a 4Ω load and 2.2W output power to an 8Ω load with a guaranteed THD of less than 10% at a supply voltage of 6V. The audio power amplifier has fewer peripheral components and better sound quality.
Load: 4Ω, Power: 3.5W typical.
Voltage: DC6V.
Turn-off current typical: 0.7μA
Operating voltage range: DC2-6V
Built-in power-on surge pulse suppression circuit
Board specifications 50 * 44 * 22mm (length * width for PCB specifications, height including components)
