AS3543 - High End Stereo Audio Codec

General Description

The AS3543 is an ultra low power stereo audio codec and is designed for Portable Digital Audio Applications.

It allows high-end quality playback with up to 100dBA SNR and recording in FM quality.

Key Features

  • 2 DCDC converters for core and memory/periphery supply as well as 4 LDOs. Both DCDC converter feature DVM (dynamic voltage management) with an selectable timing for the voltage stepping. The different regulated supply voltages are programmable via the serial control interface. The step-up converter for the backlight can operate up to 15V (with an external transistor even higher) in voltage and current control mode. An internal voltage protection is limiting the output voltage in the case of exte.

Technical coantmesntAsGtill valid AS3543 High End Stereo Audio Codec with System PMU Data Sheet 1 General Description The AS3543 is an ultra low power stereo audio codec and is designed for Portable Digital Audio Applications. It allows high-end quality playback with up to 100dBA SNR and recording in FM quality. With one microphone (including pre-amplifier and supply for an electret microphone) and two line inputs, it allows connecting a variety of audio inputs. The different audio signals can be mixed via a 6-channel mixer and fed to either a headphone output for 16 /32 headsets or a line output. Both outputs have a ground noise cancellation to use it e.g. in car docking stations.
