AAT5101 Overview
The AAT5101 is a high efficiency, 2.5W mono class D audio power amplifier. The low noise, filterless PWM architecture eliminates the output filter, reduces the external ponent count and system cost, and simplifies system design. With high efficiency of up to 92% and the industry lowest 1.35mA quiescent current, it increases battery lifetime and dramatically lowers the junction temperature. The space saving wafer-level chip scale package (WLCSP) and minimum external ponent requirements make it ideal for cellular phones and PDAs. With high PSRR, low THD+N, and 91dB SNR, the AAT5101 guarantees clean sound across the wide audio output power range and the full audio frequency domain. Short circuit and thermal protection with self-recovery prevents the device from being damaged during over current conditions. In cellular phones, the earpiece, speaker phone and melody ringer can each be driven...
