LM48901 Quad Class D Spatial Array



Texas Instruments LM48901 Quad Class D Spatial Array

Texas Instruments' amplifier creates an enhanced sound stage for portable multimedia devices

Texas Instruments' LM48901 is a quad Class D amplifier that utilizes Texas Instruments’ proprietary spatial sound processor to create an enhanced sound stage for portable multimedia devices. The Class D output stages feature Texas Instruments’ edge rate control (ERC) PWM architecture that significantly reduces RF emissions while preserving audio quality and efficiency. The LM48901’s flexible I²S interface is compatible with standard serial audio interfaces. A stereo differential-input ADC gives the device the ability to process analog stereo audio signals.   LM48901 Datasheet
