STEVAL-CCA009V1
Description
The STEVAL-CCA009V1 demonstration board is
designed to evaluate the TS4601B, a stereo
headphone driver dedicated to high audio
performance and space constrained applications.
It is based on low power dissipation, amplifier
core technology with capacitor-less outputs and
an I²C interface.
The STEVAL-CCA009V1 demonstration board
can drive at a minimum 0.9 Vrms output voltage
into 16 Ω and 1.6 Vrms into 10 kΩ, whatever the
power supply voltage, in the range from 2.9 V to
5.5 V.
The I²C interface is used to control the volume by
means of 64 steps from -60 dB to +4 dB and to
configure the device in multiple modes.
The traditionally used output-coupling capacitors
can be removed and a dedicated common-mode
sense pin suppresses parasitic noise from the
jack.
TS4601B control software is also provided.
