The CXAR41194 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 CXAR41194 has build-in shutdown control for pop/click-free on/off control.

产品概述 返回TOP
The CXAR41194 is a 2Vrms to 3Vrms pop/click-free 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 CXAR41194 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 CXAR41194 has build-in shutdown control for pop/click-free on/off control.
Using the CXAR41194 in audio products can reduce component count compared to traditional methods of generating a 3Vrms output. The CXAR41194 doesn't require a power supply greater than 5V to generate an 8.5VPP output, nor does the device require a split rail power supply. The CXAR41194 integrates a charge pump to generate a negative supply rail that provides a clean, pop/click-free ground-biased 3Vrms output.
The CXAR41194 is available in Green MSOP-10 package. It operates over an ambient temperature range of -40℃ to +85℃.
