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).
