Circuits

Audio DAC integrates stereo line drivers.

Supplied as 14-pin SOIC, CS4354 uses on-chip charge pump to generate negative supply and outputs ground-centered, 2 Vrms filtered line level signal from 5 V supply. This optimizes low-frequency response and audio quality while eliminating need for DC blocking capacitors, mute and pop suppression circuits, and high-voltage power supply. Supporting 24-bit conversion and automatic detection of audio...
