DESCRIPTION
Operating from a 5V power supply, EUA2035 is capable of delivering 3W/ channel of continuous output power to a 4Ω load with 10% THD+N. Moreover the AGC can adapt the output clip caused by power supply voltage down with battery. The new filterless architecture allows the device to drive the speaker directly, without low-pass output filters, which will save system cost and PCB area. The EUA2035 also features short-circuit and thermal protection preventing the device from being damaged during a fault condition. The EUA2035 is available in 24-pin SSOP package. FEATURES
