产品概述 返回TOP
The CXAR41161 CXAR41161A is a stereo, differential input, single supply,and cap-free line driver, which is available in SOP-14 and TSSOP-14 packages. The CXAR41161 CXAR41161A 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. CXAR41161 CXAR41161A has shutdown and under-voltage detector function for Depop solution. The CXAR41161 CXAR41161A is capable of driving 2.1Vrms at 3.3V into 2.5k load, and provides short-circuit and thermal rotection.
