The CXAR4175 is a stereo, single supply and cap-free line driver, which is available in TQFN4x4-20B, TSSOP-16, and SOP-14 packages. The CXAR4175 is a ground-reference output and doesn’t need the output capacitors for DC blocking. The advantages of eliminating the output capacitor are saving the cost, eliminating component height, and improving the low frequency response. The external gain setting is recommended using from -1V/V to -10V/V. High PSRR provides increased immunity to noise and RF rectification. The independent shutdown control of CXAR4175 is for right channel and left channel. The CXAR4175 is capable of driving 2Vrms at 3.3V into 600W load, and provides thermal protection
