5 V Stereo, 192 kHz D/A Converter with Line Driver

The CS4354 is a 24-bit, 192 kHz stereo audio digital/analog converter (DAC) with a 101 dB dynamic range and on-chip 2 VRMS line driver working from a single 5 V power supply. Based on a charge-pump architecture, this IC outputs a 2 VRMS voltage without the need for a high voltage regulator and features a ground-centered output architecture removing the need for external DC blocking capacitors and any pop prevention circuit. The results is a reduction in external component and valuable.

Features

  • Single-ended ground centered analog architecture
  • No DC-blocking capacitors required
  • Integrated step-up/Inverting charge pump
  • Filtered line-level outputs
  • Low-latency digital filtering
