Filter-free stereo 2.8 W Class-D audio power amplifier demo board with selectable 3D sound effects based on the TS4999

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.

Pop and click reduction circuitry provides low on/off switch noise while allowing the device to start within 8 ms.

3D enhancement effects are selected through one digital input pin that allows more amazing stereo audio sound.

Two standby pins (active low) allow each channel to be switched off separately.

The TS4999 is available in a 18 bumps Flip-Chip package.
