一.产品概述oWu嘉泰姆


   The CXAB4125 CXAB4126 is a Class-AB audio power amplifier designed oWu嘉泰姆

for mobile phones and other portable communication devices. It is capable oWu嘉泰姆

of delivering 1.2 watts of continuous average power to an 8Ω BTL load withoWu嘉泰姆

less than 1% distortion (THD+N) from a 5VDC power supply. oWu嘉泰姆

  The CXAB4125 CXAB4126 was designed specifically to provide high quality oWu嘉泰姆

output power with a minimal amount of external components. It does not require oWu嘉泰姆

output coupling capacitors or bootstrap capacitors. And with ultra low oWu嘉泰姆

shutdown current, the CXAB4125 CXAB4126 is ideally suited for mobile phone and oWu嘉泰姆

other low voltage applications where minimal power consumption is a oWu嘉泰姆

primary requirement. With special pop-click eliminating circuit, the oWu嘉泰姆

CXAB4125 CXAB4126 provides perfect pop-click characteristic during turn-on and oWu嘉泰姆

turn-off transitions. oWu嘉泰姆

 The CXAB4125 CXAB4126 is unity-gain stable and can be configured by external oWu嘉泰姆

gain-setting resistors.oWu嘉泰姆
