The CXAR41197 is a 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 CXAR41197 also has a single rail-to-rail 5th-order video filter with a -3dB bandwidth of 8MHz and a slew rate of 35V/μs. It operates from 3.0V to 5.5V power supply. The device is ideal for single supply electronics where size and cost are critical design parameters.nSE嘉泰姆

The CXAR41197 is capable of driving 3Vrms into a 2.5kΩ load with 5V 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 CXAR41197 has build-in shutdown control for pop/click-free on/off control. The CXAR41197’s video driver employs an internal level shift circuit that avoids sync-pulse clipping and allows DC-coupled output.nSE嘉泰姆

Using the CXAR41197 in audio products can reduce component count compared to traditional methods of generating a 3Vrms output. The CXAR41197 doesn't require a power supply greater than 5V to generate an 8.5V_PP output, nor does the device require a split rail power supply. The CXAR41197 integrates a charge pump to generate a negative supply rail that provides a clean, pop/click-free ground-biased 3Vrms output.nSE嘉泰姆

The CXAR41197 is available in Green TSSOP-20 package. It operates over an ambient temperature range of -40℃</span> to +85℃</span>.nSE嘉泰姆
