The CXAR4177 CXAR4177A is a stereo, fixed gain, and cap-free headphone driver which is available in TQFN4x4 20-pin, TQFN3x3 16-pin (CXAR4177A) or TSSOP-16 package. Dual supply voltage provides higher efficiency and better power ripple rejection. The CXAR4177 CXAR4177A is designed with ground-reference output and no need the output capacitors for DC blocking. The advantages of eliminating the output capacitor are saving the cost, PCB’s space, and component height. The built-in gain setting can minimize the external component counts and save the PCB space. High PSRR provides increased immunity to noise and RF rectification. In addition to these features, a fast start-up time and small package size make the CXAR4177 CXAR4177A an ideal choice for portable multimedia devices. Moreover, the CXAR4177 CXAR4177A is also equipped other features. For example, at THD+N=1%, it is capable of driving 200mW at VDD =3.3V, PVDD =5.0V into 16W. In addition, it provides thermal and short circuit protections.
