2W Stereo Audio Amplifier with DC Volume Control and Selectable Gain CXAR41279 supports the Bridge-Tied Load (BTL) mode for driving the speakers, Single-End (SE) mode for driving the headphone

   产品概述 返回TOPUtI嘉泰姆

The CXAR41279 is a stereo audio power amplifier in both 28pin TSSOP and TQFN thermal pad package. It can deliver 2.0W continuous RMS power into 4Ω load per channel in Bridge-Tied Load (BTL) mode at 5V supply voltage. Its THD is smaller than 1% under the above operation condition. To simplify the audio system design in the notebook application, CXAR41279 supports the Bridge-Tied Load (BTL) mode for driving the speakers, Single-End (SE) mode for driving the headphone. For the low current consumption applications, the Shutdown mode is supported to disable the CXAR41279 when it is idle. The current consumption can be reduced below 2μA. The internal DC volume gain setting is ranged from 0dB to -78dB. We can activate the internal DC volume control by setting the Mode pin high, and setting the Vol value to get the expected DC volume gain. The CXAR41279 is with the flexible for the user to select the internal embedded gain setting or external gains through the gain_sel pin. Setting the gain_sel pin low is to activate the internal gain settings, setting high for external gains.
