Package: DIP 16 Pin Type

Manufacturer: CCMIC


CM2038A audio amplifier


The CM2038A is a dual BTL audio power amplifier. When the supply voltage is 6V, to ensure that the THD is less than 10% of the cases, to 4Ω load to provide 3.5W of output power or 8Ω load to provide 2.2W of output power. The audio power amplifier peripheral components rarely, high-quality output power.

The CM2038A features external control, low power shutdown mode and internal thermal protection, and reduces “start-up surge” in the circuit.
