This demonstration board is designed to evaluate the performances of TS4999, that is a stereo fully differential Class-D power amplifier.
It can drive up to 1.35 W into a 8 Ω load at 5 V per channel. The device has four different gain settings utilizing two discrete pins, G0 and G1.
3D enhancement effects are selected through one digital input pin that allows more amazing stereo audio sound.
