一.产品概述jHO嘉泰姆

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

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

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

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

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

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

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

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

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

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

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

turn-off transitions. jHO嘉泰姆

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

gain-setting resistors.jHO嘉泰姆
