The CS42L51 delivers excellent audio performance while providing portable device developers with an innovative solution that maximizes battery life while minimizing end-product form factors. The CS42L51’s key distinction is that it operates from a single, 1.8 V power supply for low power consumption, yet delivers plenty of output power, 46 mW, into stereo 16 ohm headphones for a great listening experience. This highly integrated 24-bit, 96 kHz stereo CODEC is based on a multibit Delta-Sigma architecture which allows infinite sample rate adjustment between 4 kHz and 100 kHz. By generating its own on-chip negative power supply voltage, the CS42L51 provides ground-centered outputs, which eliminates costly, space-consuming DC blocking capacitors that some competing solutions require. The elimination of these capacitors not only reduces the implementation cost but it also greatly simplifies product design and saves valuable circuit board space. This next-generation CODEC is an ideal choice for any portable audio product developer. |
