ams-OSRAM AG Interface - CODECs AS3518-T

The AS3518-T is a low power stereo audio codec designed for portable digital audio applications, capable of CD-quality playback and recording. It features multi-bit Sigma Delta converters with an 18-bit DAC and a 20-bit ADC, offering a signal-to-noise ratio of 94dB and 90dB respectively. The codec supports a variety of audio inputs and outputs, including a microphone input with adjustable gain settings and three line inputs, all managed through a 10-channel mixer. Power consumption is less than 20mW in playback mode, and the device includes advanced power management capabilities, such as programmable supply voltages and a built-in Li-Ion battery charger. The AS3518 operates with a single supply voltage ranging from 1.0V to 5.5V and incorporates a phase-locked loop for generating the internal master clock. Additionally, it features a real-time clock, general-purpose ADC, and multiple interfaces including I¬=S and a two-wire serial control interface. This codec is suitable for applications in portable digital audio players and smartphones, making it a versatile choice for engineers looking to integrate audio functionality into their designs.
