Description
The STw5200 is a 24-bit high performance DAC for mobile handset application with 103 dB dynamic range for the whole audio path. The device can be driven either by the system clock or by the 32 kHz RTC clock. STw5200 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).
