Texas Instruments LM48821TLEVAL
The LM48821 is direct coupled, ultra low noise, 52mW differential input stereo headphone amplifier with I2C control. The LM48821 is designed to meet the demands of mobile phones and other portable communication devices. It is capable of delivering 52 milliwatts of average power to a 16 ohm load with less than 1% distortion (THD+N) from a 3V DC power supply.
The LM48821TLEVAL is an evaluation board designed to ease evaluation and effort during the development of a circuit using the LM48821TL. It is an easy-to-use stand-alone board that requires power and GND, a differential input signal and an output load.
