AW8735TQR

Class-K Audio Amplifier with RF-TDD Suppression and Unique FM Mode

The AW8735 is a powerful Class-K audio amplifier with AB/D output mode selection; the  power  stage voltage can select supplied by charge pump or straightly supplied by battery. AW8735 features unique FM mode and Net audio mode, designed for  mobile  phone  audio  application  and development. The AW8735 realizes five kinds of working mode by one-wire pulse control technology, can offer the needed working mode according to different power of the speaker. All five kinds of mode with NCN technology effectively prevent the crack noise.The AW8735 features the RNS function which greatly reduces RF-TDD Noise.The AW8735 features Net audio technology which can further reduces RF-TDD noise, an acceptable audible level to the customer. The AW8735 features a built-in charge pump converter generates a 6.3V supply voltage. This provides a louder audio output than a stand-alone amplifier directly connected to the battery. The AW8735 features 2.3W output power (10% THD+N) into 8Ω load at 4.2V battery voltage. The AW8735 features the NCN function, which adjusts the system gain automatically while detecting the “Crack” distortion of output signal, protects the speaker from damage at high power levels and brings the most comfortable listening experience to the customers.
