Description of the evaluation board
The evaluation board is divided into two parts. One part includes a typical application for the
TS4956 and provides connectors for stereo headphones with a load of 16/32Ω. The other
part allows you to evaluate I
opto-separated in order to obtain better suppression of noise caused by the PC power
supply.
With this evaluation board you can use the TS4956 amplifier in most typical applications
with typical external components. You can also use the on-board I
controller to control the TS4956 amplifier (see

For I
and to the on-board I

One solution is to use the V
connector Cn4 using a jumper. Note that in this case the supply current is higher than
the TS4956 supply current itself due to additional current flowing through the on-board
I
The second solution is to use an external power supply connected to connector Cn4 to
supply the I
evaluation board is equal to the supply current of the TTS4956 itself. (See
