The TPA2050D4 is a stereo Class-D power amplifier along with a stereo DirectPath™ headphone
amplifier. Both input channels have 32-step volume control and the DirectPath™ headphone amplifier has
a 4-step level gain control with power limiter. The volume is controlled through an I
2
C™ interface. All
amplifiers have output short-circuit and thermal-overload protection.
The TPA2050D4 evaluation module(EVM) is a complete, stand-alone audio board. It contains the
TPA2050D4 WCSP(YZK) Class-D audio subsystem.
All components and the EVM are Pb free.
