AW8733B is a powerful Class-K audio amplifier that features RNS (RF-TDD Noise Suppression), NCN (Non-Crack-Noise) and EEE (Enhanced Emission Elimination).
AW8733B is a Class-K audio amplifier upgraded from AW8733A, noise, power, efficiency and other indicators have been improved.
AW8733B features the RNS function which greatly reduces RF-TDD Noise.
AW8733B features a built-in charge pump converter generates a 6.5V supply voltage. This provides a louder audio output than a stand-alone amplifier directly connected to the battery.
AW8733B features 2W output power (1% THD+N) into 8Ω load at 4.2V battery voltage.
AW8733B 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.
AW8733B is available in a QFN 3mm x 3mm x 0.75mm -20L Package. It is specified over the extended -40℃ to +85℃ temperature range.
