TLV320DAC23 具有耳机放大器的低功耗立体声音频 DAC
TLV320DAC23 描述
The TLV320DAC23 is a high-performance, four-channel digital-to-analog (D/A) converter designed for use in professional audio applications. The TLV320DAC23 supports 16- to 24-bit linear PCM input data, with sampling frequencies up to 216kHz. The TLV320DAC23 features lower power 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 D/A conversion sub-system.
The TLV320DAC23 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.
