Class G capless headphone amplifier based on TS4621E

STEVAL-CCA025V1

Overview

The STEVAL-CCA025V1 demonstration board is designed to aid in the evaluation of the TS4621E audio differential input stereo headphone amplifier. The TS4621E device is soldered on a four-layer PCB. An on-board RS-232 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.
You can also use the connectors on the demonstration board to directly control the features through another I²C interface.

Main features

Power supply range: 2.3 V to 4.8 V
0.6 mA/channel quiescent current
2.1 mA current consumption with 100 μW/channel (10 dB crest factor)
0.006% typical THD+N at 1 kHz
100 dB typical PSRR at 217 Hz
Zero pop and click
I²C interface for volume control
Digital volume control range: -60 dB to +4 dB

100 dB of SNR A-weighted at G = 0 dB
Independent right and left channel enable control
Integrated high-efficiency buck converter
Low standby current: 5 μA max
No output coupling capacitors (thanks to the internal negative supply)
Thermal shutdown and short-circuit protection
RoHS compliant
