Fangtek ft4266
The ft4266 is a dual bridge-connected audio power amplifier. When supplied with 5V voltage, the ft4266 can deliver 1.3W to a 4Ω load with THD+N less than 1.0%. The ft4266’s dual power amplifier topology provides high quality dual outputs while requiring fewer external components and consuming minimum PCB area.GENERAL DESCRIPTION
The ft4266 features shutdown power-saving control suitable for use in portable devices. When the power-saving mode is activated, only 0.04μA current is consumed on the device. Other features such as thermal shutdown protection and “clicks and pops” reduction during power-up ensure a safe and reliable operation in portable audio applications.FEATURES
