It is a low noise, filterless PWM architecture eliminates the output filter, reducing external component count, system cost, and simplify design. The LY8005 is designed to meet of mobile phones and other portable electronic devices. The LY8005 is a single 5V supply, it is capable of driving 4Ω speaker load at a continuous average output of 2.3 W with 10% THD+N. The LY8005 has high efficiency with speaker loads compared to a typical Class AB amplifier. In cellular handsets, the earpiece, speaker phone, and melody ringer can each be driven by the LY8005.The gain of the LY8005 is externally configurable which allows independent gain control from multiple sources by summing the signals. Output short circuit and thermal overload protection prevent the device from damage during fault conditions. APPLICATION „ P...
