Texas Instruments  TPA2054D4YZKEVM

 The TPA2054D4 is a stereo Class-D power amplifier with an integrated stereo DirectPath(TM) headphone amplifier. This device has 3 input channels, offering a 32-step volume control and the DirectPath(TM) headphone amplifier has a 4-step level gain control with power limiter. The volume is controlled through an I2C(TM) interface. All amplifiers have output short-circuit and thermal-overload protection. The TPA2054D4YZK evaluation module (EVM) is a complete, stand-alone audio board that contains the TPA2054D4 (in WCSP) and interfaces to a PC via a USB connector. All components on the EVM are Pb free.
