Manufacturer: SJ


SJ2038 pinout datasheet


The SJ2038 is a dual BTL audio power amplifier. When the supply voltage is 6V, it can provide 3.5W output power to 4Ω load or 2.2W output power to 8Ω load under the condition of ensuring THD less than 10%. The audio power amplifier has very few external components and high-quality output power.

The SJ2038 circuit features external control, low power shutdown mode and internal thermal protection, and reduces “power-on surge” in the circuit.
