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 PTE

™ 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 PTE

™ mode, when the PLL is driven

by the 32 kHz frequency.
