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).
