Product Overview

STEVAL-CCA025V1 demonstration board is designed to aid in the evaluation of the TS4621E audio differential input stereo headphone amplifier. It is a class G stereo headphone driver dedicated to high audio performance, high power efficiency and space constrained applications. It is based on the core technology of a low power dissipation amplifier combined with a high efficiency buck converter for supplying this amplifier. When powered by a battery, the buck converter generates the appropriate voltage to the amplifier depending on the amplitude of the audio signal to supply the headsets. The TS4621E device is soldered on a four layer PCB. An on board RS232 to I2C 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 TS4621E, such as gain, mode, mute, standby and register status. The connectors on the board is used to directly control the features through another I2C interface.
  • Power supply range of 2.3V to 4.8V
  • Quiescent current of 0.6mA/channel, Low standby current
  • 2.1mA current consumption with 100uW/channel
  • Zero pop and click
  • I2C interface for volume control
