LM48901 Quad Class D Spatial Array

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

LM48901 Quad Class D Spatial ArrayTexas 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.
