AW8733ATQR

The AW8733A features proprietary RNS technology to effectively suppress TDD noise. It boosts voltage to 6.3V within the lithium battery voltage range, delivering 2.0W output power to an 8Ω speaker at a 4.2V supply voltage with THD+N = 10%. The unique No Clip Noise (NCN) function automatically adjusts the amplifier gain based on the output signal level, providing a more comfortable listening experience. A single-wire pulse interface controls four operating states, enabling selection of different gain settings and NCN modes. Comprehensive protection features prevent chip damage under abnormal operating conditions. Minimal external components are required, making it ideal for portable applications. Available in a compact 3mm×3mm 20-Pin TQFN package with a small PCB footprint. Rated operating temperature range: -40°C to 85°C.
