The CXAR41192 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.KRh嘉泰姆

The CXAR41192 is capable of driving 2Vrms into a 2.5kΩ load with 3.3V supply voltage. The device has differential inputs 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 CXAR41192 has build-in shutdown control for pop/click-free on/off control.KRh嘉泰姆

Using the CXAR41192 in audio products can reduce component count compared to traditional methods of generating a 2Vrms output. The CXAR41192 doesn't require a power supply greater than 3.3V to generate a 5.6V_PP output, nor does the device require a split rail power supply. The CXAR41192 integrates a charge pump to generate a negative supply rail that provides a clean, pop/click-free ground-biased 2Vrms output.KRh嘉泰姆

The CXAR41192 is available in Green TSSOP-14 package. It operates over an ambient temperature range of -40℃</span> to +85℃</span>.KRh嘉泰姆
