Description
The STw5210 is a 24-bit high performance DAC for mobile handset application with 103 dB dynamic range for the whole audio path. It embeds an innovative PTETM function that reduces drastically the whole application power consumption. In this mode, the music is played back autonomously, while the whole system is switched to power saving condition. The IC is then driven by the 32 kHz clock only. The device can be used also in a conventional way (continuous mode) and be driven by the system clock. STw5210 is very easy to integrate and thanks to its embedded power management, it can be directly connected to the battery. The device foot print is very small as the EBOM is reduced to a few components. The 50 mW headset amplifier is of "True-ground" type (no coupling capacitor) and no additional quartz is required in PTETM mode, when the PLL is driven by the 32 kHz frequency.
