LY8210

® Rev. 1.7 2.5 W/CH Stereo Class D Audio power Amplifier (WCSP/ TSSOP) GENERAL DESCRIPTION The LY8210 is a high efficiency, 2.5 W stereo class D audio power amplifier. It is a low noise, filterless PWM architecture eliminates the output filter, reducing external component count, system cost, and simplify design. The LY8210 is designed to meet of Multimedia application includes mobile phones and other portable electronic devices. The LY8210 is a single 5V supply, it is capable of driving 4Ω speaker load at a continuous average output of 2.5 W/CH with 10% THD+N. In cellular handsets, the earpiece, speaker phone, and melody ringer can each be driven by the LY8210. Output pin short circuit ( short to output pin, short to ground and short to VDD ) protection prevent the device from damage during fault conditions. LY8210 FEATURES „ 2.5 W/CH Into 4Ω from 5V power supply at THD = 10% (Typ.). „ 2.5V~5.5V Power supply. „ Low shutdown Current. „ Low Quiescent Current. „ Minimum external components. „ No output filter required for inductive loads. „ Output Pin Short-Circuit Protection (Short to Output Pin, Short to GND, Short to VCC) „ Low noise during turn-on and turn-off transitions. „ Lead free and green package available.
