| Product Brief VOLTAGE DETECTOR Amplifier with 4 Selectable Gain Setups and Input Mux 2.7W Stereo Audio Power Description The AZ70XXis a Class AB stereo audio power amplifier The AA4006 series ICs are under voltage detectors with with headphone driver, which can deliver 2.7W into 3 a built in voltage threshold and low power consumption. speakers with 5.0V power supply and THD+Naccurately The AZ70XX are specifically designed to less than 10%. It is designed specially for Notebook PC and portamonitor power supplies. ble media player applications. The AZ70XX use a precision on-chip voltage reference The a comparator to measure the input operating voltage. and AA4006 features stereo full differential input or 2 sets of ICs canSingle-Ended audio input. There are 4 difThese stereo accurately reset the system after detecting ferent gain the timeat BTL Mode -6dB, 10dB, 15.6dB and voltage at settings of switching power on and instanta21.6dB, changed in various CPU systems andpins.
