AW8733A

AW8733A Datasheet Jun 2012 V1.0 2W Class-K Audio Amplifier with RF-TDD Suppression and NCN Features General Description l y Built-In RNS Function，Excellent TDD Suppression y NCN Function Protects the Speaker y EEE Function，Greatly reduces EMI over the full bandwidth y 2.0W into 8Ω at 4.2V(10% THD+N) y 4 Selectable Gain，12dB，16dB，24dB， 27.5dB y 4 Mode selected by one-wire pulse y Excellent Pop-Click Suppression y Short-Circuit and Thermal Protection y ±8KV HBM ESD，±450mA Latch-up y Small 3mm×3mm 20-Pin TQFN Package The AW8733A is a powerful Class-K audio amplifier that features RNS (RF-TDD Noise a Suppression), NCN (Non-Crack-Noise) and EEE i (Enhanced Emission Elimination). t The AW8733A features the RNS function which greatly reduces RF-TDD Noise. n The AW8733A features a built-in charge pump converter generates a 6.3V supply voltage. This e provides a louder audio output than a stand-alone fid amplifier directly connected to the battery. The AW8733A features 2W output power (10% THD+N) into 8Ω load at 4.2V battery voltage. The AW8733A features the NCN function, which n adjusts the system gain automatically while detecting the “Crack” distortion of output signal, protects the speaker from damage at high power Applications olevels and brings the most comfortable listening experience to the customers. y Cellular Phones y Portable Audio Devices C The AW8733A is available in a small 3mm×3mm 20-Pin TQFN Package. It is specified over the extended -40℃ to +85℃ temperature...
