一.产品概述1jP嘉泰姆


  The CXAB4124 is a Class-AB audio power amplifier designed for mobile phone, MID and other portable communication devices. It is capable of delivering 1.1 watts of continuous average power to an 8Ω BTL load with less than 1% distortion (THD+N) from a 5VDC power supply. The CXAB4124 was designed specifically to provide high quality output power with a minimal amount of external components. It does not require output coupling capacitors or bootstrap capacitors. And with ultra low shutdown current, the CXAB4124 is ideally suited for mobile phone , MID and other low voltage applications where minimal power consumption is a primary requirement. With special pop-click eliminating circuit, the CXAB4124 provides perfect pop-click characteristic during turn-on and turn-off transitions. The CXAB4124 is unity-gain stable and can be configured by external gain-setting resistors.1jP嘉泰姆
