AV5230
General Description
High Quality PTE™ audio DAC with SMABTM headset amplifier
The AV5230 is ST-Ericsson’s new generation of PTETM DAC+ Headset amplifier ICs that further extend audio playback time of mobile applications, even when playing high-quality audio. It embeds the innovative SMABTM headset amplifier (Class-G technology from ST-Ericsson), scaling the IC power to the audio signal amplitude which is played. As with the previous PTETMdevices, the AV5230 provides an amazing 102 dB signal-to-noise ratio (SNR) for the whole audio path. It can be directly supplied from the battery, and use a true-ground type of amplifier.
