Description

The STEVAL-CCA025V1 demonstration board is

designed to aid in the evaluation of the TS4621

audio differential input stereo headphone

amplifier. The TS4621 device is soldered on a

four-layer PCB. An on-board RS-232 to I

interface renders the board easy to control from a

personal computer through a serial port.

The software provided with the board controls all

features of the TS4621, such as gain, mode,

mute, standby and register status.

You can also use the connectors on the

demonstration board to directly control the

features through another I
