Features & Applications

The STEVAL-CCA025V1 is a evaluation board for the TS4621E class G capless headphone amplifier.

This 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.

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
