Description
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.
