     CXAR41179是一款采高压工艺并集成反相电荷泵电源的G类音频放大器，透过G类输出级提供良好的性能，相较于AB类组件具有更高的效率，不存在与D类放大器相关的EMI干扰。CXAR41179在单电源2.5~5V供应，低耗电流3.8mA，16Ω同相双负载下，最大输出功率达120mW (THD+N=1%)，且在1KHz拥有80dB PSRR。G类输出级架构无需输出大电容以及拥有超低THD+N，使其适合于行动电话以及其它可携式设备的耳机放大应用。CXAR41179采用TDFN-12与WCSP-12 (1.5mmX2mm)封装。CXAR41179 is a dual audio power amplifier designed for portable communication device applications such as mobile phones. CXAR41179 operates from a single 2.5V to 5.5V supply, consumes only 3.8mA of supply current, capable of delivering 30mW of continuous average power into a 16Ω load from a 3V power supply with a THD+N of 1%. Base on the power supply delivered to the device, an internal power management block generates a negative voltage. Thus, the internal amplifiers provide outputs referenced to Ground. In this configuration, the two external heavy coupling capacitors can be removed. It offers significant space and cost savings compared to a typical stereo application. CXAR41179 has an internal gain of – 1.5V/V with low 0.03% THD+N performance. An 80dB at 1kHz power-supply rejection ratio (PSRR) allows these devices to operate from noisy digital supplies without an additional linear regulator. Comprehensive click-and-pop circuitry suppresses audible clicks and pops on startup and shutdown. Other features include short-circuit and thermal-overload protection, and are specified over the extended -40°C to +85°C temperature range. The device is available in tiny 12- bump WCSP (1.5mm×2mm) and TDFN-12 packages.
