   产品概述 返回TOPN74嘉泰姆

   CXAR41277 is a stereo audio power amplifier in 20pin TSSOP thermal pad package or 20-pin TQFN 4X4. It can drive 2W 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 and to enlarge the driving power, CXAR41277 supports the Bridge-Tied Load (BTL) mode for driving the speakers. For the low current consumption applications, the SHDN mode is supported to disable CXAR41277 when it is idle. The current consumption can be reduced to 150μA (typically). Amplifier gain is internally configured and controlled by two terminals (GAIN0, GAIN1). BTL gain settings of 6dB, 10dB, 15.6dB, 21.6dB are provided.
