AS3517 Description

The AS3517 is an integrated audio codec from ams OSRAM, designed to deliver high-quality audio performance in a compact and efficient package. This codec features a combination of advanced analog-to-digital converters (ADCs) and digital-to-analog converters (DACs), making it suitable for a wide range of audio applications. The AS3517 supports a dynamic range of 83 dB for ADCs and 88 dB for DACs, ensuring clear and distortion-free audio signals. Its signal-to-noise ratio (SNR) is 90 dB for ADCs and 94 dB for DACs, which further enhances the clarity and fidelity of the audio output.

The AS3517 operates with a supply voltage range of 2.8V to 3.6V for both digital and analog circuits, providing flexibility in power management while maintaining high performance. It utilizes an I2S data interface, which is widely used in audio systems for its simplicity and reliability. The codec includes two ADCs and two DACs, enabling simultaneous processing of stereo audio signals. Additionally, the AS3517 incorporates sigma-delta modulation, a technique that improves the accuracy and precision of the conversion process.

Packaged in a surface-mount 81-CTBGA format, the AS3517 is designed for easy integration into modern electronic devices. It is available in tray packaging and has a moisture sensitivity level (MSL) of 3, which means it can be stored for up to 168 hours before assembly without requiring additional moisture protection.
