   产品概述 返回TOPcf5嘉泰姆

The CXAR41162 is a 2Vrms to 3Vrms Pop&Click-less stereo line driver designed to allow the removal of the output dc-blocking capacitors for reduced component count and cost. The device is ideal for single supply electronics where size and cost are critical design parameters. The CXAR41162 is capable of driving 3Vrms into a 2.5kΩ load with 5V supply voltage. The device has single input and uses external gain setting resistors, that supports a gain range of ±1V/V to ±10V/V. The use of external gain resistors also allows the implementation of a 2nd order low pass filter to compliment DAC's and SOC converters. The CXAR41162 has build-in shutdown control for Pop&Click-free on/off control. Using the CXAR41162 in audio products can reduce component count compared to traditional methods of generating a 3Vrms output. The CXAR41162 doesn't require a power supply greater than 5V to generate its 8.5VPP output, nor does it require a split rail power supply. The CXAR41162 integrates its own charge pump to generate a negative supply rail that provides a clean, pop&click-less ground biased 3Vrms output. The CXAR41162 is available in Green MSOP-10 (Exposed Pad) package. It operates over an ambient temperature range of -40℃ to +85℃.
