STw5200
General Description
The STw5200 is a 24-bit, high-quality DAC for portable applications, with 102 dB signal-to-noise ratio (SNR) for the whole audio path. The power consumption can be scaled down by adjusting the audio quality from 102 to 99 dB SNR (4-steps). The STw5200 is easy to integrate as it can be directly supplied by the battery. Advanced IPs are included to reduce the number of external components and the footprint, including a headset driver with no coupling capacitor.
