AW8733ATQR

2W Class-K Audio Amplifier with RF-TDD Suppression and NCN

The AW8733A is a powerful Class-K audio amplifier that features RNS (RF-TDD Noise Suppression), NCN (Non-Crack-Noise) and EEE (Enhanced Emission Elimination). The AW8733A features the RNS function which greatly reduces RF-TDD Noise. The AW8733A 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 AW8733A features 2W output power (10% THD+N) into 8Ω load at 4.2V battery voltage. The AW8733A 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.
