AU3138 is a Class D stereo audio amplifier delivering 10W per channel with high efficiency and low quiescent current. It supports stereo speaker loads as low as 3.2Ω. In 1SPW mode, the quiescent current is only 16mA (12V), extending audio playback time and making it suitable for Bluetooth speakers, battery-powered devices, and other power-sensitive applications. The device features spread-spectrum control for enhanced EMI suppression, allowing the use of low-cost ferrite bead filters while meeting EMC requirements to reduce system cost. For applications such as TVs, the AU3138M/AU3138P variants feature an undervoltage protection threshold of 7.5V to effectively prevent pop noise during power-down; for battery-powered or low-supply-voltage applications such as audio systems, the AU3138S/AU3138T variants support operating voltages as low as 3.5V. To simplify design, the AU3138 integrates comprehensive protection features including undervoltage protection, overvoltage protection, power limiting, short-circuit protection, thermal protection, and DC speaker protection, all with auto-recovery capability.
