Texas Instruments  LM49150TLEVAL

The LM49150 is an integrated stereo subsystem with a highly efficient Class D speaker amplifier, ground referenced headphone amplifier and low power earpiece bypass path in a 20-bump micro SMD package. The LM49150 is designed to meet the demands of mobile phones and other portable communication devices. It is capable of delivering 1.25W of average power into an 8 ohm load and 42 milliwatts of average power to a 32 ohm load with less than 1% distortion (THD+N) from a 5V DC power supply to VDD_LS and VDD.

The LM49150TLEVAL is an evaluation board designed to ease evaluation and effort during the development of a circuit using the LM49150TL. The evaluation board comes with an I2C card and cable. It is an easy-to-use stand-alone board that requires power and GND, an I2C control signal, an input signal and output loads.
