PCM4104-EP 118dB SNR 4 通道音频 DAC（延长认证有效期）
The PCM4104 is a high-performance, four-channel digital-to-analog (D/A) converter designed for use in professional audio applications. The PCM4104 supports 16- to 24-bit linear PCM input data, with sampling frequencies up to 216 kHz. The PCM4104 features lower power consumption than most comparable stereo audio D/A converters, making it ideal for use in high channel count applications by lowering the overall power budget required for the D/A conversion subsystem.
The PCM4104 features delta-sigma architecture, employing a high-performance multi-level modulator combined with a switched capacitor output filter. This architecture yields lower out-of-band noise and a high tolerance to system clock phase jitter. Differential voltage outputs are provided for each channel and are well-suited to high-performance audio applications
