一.产品概述f6q嘉泰姆


   The CXAB4125 CXAB4126 is a Class-AB audio power amplifier designed for mobile phones and other portable communication devices. It is capable of delivering 1.2 watts of continuous average power to an 8Ω BTL load withless than 1% distortion (THD+N) from a 5VDC power supply. f6q嘉泰姆

  The CXAB4125 CXAB4126 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 CXAB4125 CXAB4126 is ideally suited for mobile phone and other low voltage applications where minimal power consumption is a primary requirement. With special pop-click eliminating circuit, the f6q嘉泰姆

CXAB4125 CXAB4126 provides perfect pop-click characteristic during turn-on and turn-off transitions. f6q嘉泰姆

 The CXAB4125 CXAB4126 is unity-gain stable and can be configured by external gain-setting resistors.f6q嘉泰姆
