The BCT8933 is a powerful Class-T audio amplifier. Using our unique Digital Power Modulation (DPM) audio algorithm, effectively eliminate audio noise, increase signal Dynamic range which will greatly improve sound quality and volume.
The BCT8933 includes a built-in 2X charge pump converter which generates a 6.3V supply voltage. This can provide a wider audio signal output range than a Traditional class D amplifier directly connected to the battery. The BCT8933 can provide 2W output power (10% THD+N) into 8Ω load from the 4.2V battery voltage.
The BCT8933 features the DPM function, which adjusts the system gain and output power automatically, protects the speaker from damage at high power levels and brings the most comfortable listening experience to the customers.
The BCT8933 is available in a small 3mm×3mm 20-Pin QFN Package. It is specified over the extended -40℃ to +85℃ temperature range.
