The CXAR4173 is a stereo, differential input, single supply, and cap-free line driver, which is available in SOP-14 and TSSOP-14 packages. The CXAR4173 is 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. CXAR4173 has shutdown and under-voltage detector function for Depop solution. The CXAR4173 is capable of driving 2.1Vrms at 3.3V into 2.5kW load, and provides short-circuit and thermal protection
