Texas Instruments  LM4675TLBD

The LM4675 is a class D filterless BOOMER audio amplifier with ultra low EMI. TI's new spread spectrum technology has been integrated with the latest BOOMER performance characteristics in a 0.5mm pitch, micro SMD package. The LM4675 is designed for high output, low EMI and space saving applications such as mobile phones and other portable communication devices. This all new BOOMER delivers typically 1.3 Watts of power output in 8 ohm load with less than 1% distortion (THD+N) from a 5V DC power supply.

The LM4675TLBD and LM4675SDBD are evaluation boards designed for rapid user evaluation and saving customers valuable development expense with faster time to market. The evaluation boards include a measurement filter and are ready-to-use in a stand-alone approach that simply requires power and GND, input signal and an output load.
