The CXAR41203 is a 1.2W, fully integrated, audio power amplifier. It is designed to maximize audio performance in portable applications such as mobile phone. The portable application requires audio power amplifier has minimum of external components and can operate from a single 2.5V to 5.5V power supply. CXAR41203 is capable of delivering 1.2W of continuous output power with typically 1% distortion (THD+N) when it drives an 8Ω speaker from a 5.0V power supply.

The CXAR41203 is a 1.2W, fully integrated, audio power amplifier. It is designed to maximize audio performance in portable applications such as mobile phone. The portable application requires audio power amplifier has minimum of external components and can operate from a single 2.5V to 5.5V power supply. CXAR41203 is capable of delivering 1.2W of continuous output power with typically 1% distortion (THD+N) when it drives an 8Ω speaker from a 5.0V power supply.
The CXAR41203 features a low power consumption shutdown mode, which is achieved by driving the shutdown pin with a logic low. Additionally, the CXAR41203 features an internal thermal shutdown protection mechanism.
The CXAR41203 does not require output coupling capacitors or bootstrap capacitors, and therefore is ideally suited for mobile phone and other low voltage applications where minimal power consumption is a primary requirement.
For maximum flexibility, the CXAR41203 provides an externally controlled gain (with resistors), as well as an externally controlled turn-on time (with the bypass capacitor). When using a 1μF bypass capacitor, it offers 145ms wake-up time when V+ is equal to 5.0V.
The CXAR41203 is available in Green TDFN-2×2-8L package. It operates over an ambient temperature range of -40℃ to +85℃.
