Description of the demonstration board
The TS4657 demonstration board has been designed for evaluation purposes. The TS4657
device is soldered on a two-layer PCB.
Some key features of the TS4657 can be directly controlled through connectors or jumpers
on the demonstration board
Table 1.
When you apply the power supply through J5, do not invert the polarity as doing so will
damage the chip.

Allows selection of level on Format1 pin. Format1 and Format2 pins select the digital
input format (see section 4.1.2 Digital audio input format in the TS4657 datasheet).
If the jumper is removed, it is possible to control the Format1 by an external logic
signal (see section 3.3 DAC and output stage performances in the TS4657
datasheet).
Allows selection of level on Format2 pin. Format1 and Format2 pins select the digital
input format (see section 4.1.2 Digital audio input format in the TS4657 datasheet).
If the jumper is removed, it is possible to control the Format2 by an external logic
signal (see section 3.3 DAC and output stage performances in the TS4657
datasheet).
Controls the chip standby (JP1:1-2 = circuit activated, 2-3 = circuit in standby mode).
If the jumper is removed, it is possible to control the standby by an external logic
signal (see section 3.3 DAC and output stage performances in the TS4657
datasheet).
Allows connection of the C6 capacitor (used for the left output filter;
