TI LM48903TLX/NOPB

The LM48903 is a stereo Class D amplifier that utilizes TI’s proprietary spatial sound processor to create an enhanced sound stage for portable multimedia devices. The Class D output stages feature National’s edge rate control (ERC) PWM architecture that significantly reduces RF emissions while preserving audio quality and efficiency. The LM48903’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. The LM48903 is configured through an |2\complement compatible interface and is capable of delivering 1.7W/channel of continuous output power into an 8Ω load with less than 10% THD+N. Output short circuit and thermal overload protection prevent the device from being damaged during fault conditions. Click and pop suppression eliminates audible transients on powerup/down and during shutdown. The LM48903 is available in space saving micro SMD package.
