产品概述
描述
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.
