Alc271x Datasheet -

If you are looking to integrate or repair devices using this chip, technical documents and components are available from authorized distributors.

: Typically shipped in a space-saving 48-pin QFN (Quad Flat No-leads) package, measuring either 6x6 mm or 7x7 mm.

High-performance Digital-to-Analog Converters (DACs) reaching up to 100dB Signal-to-Noise Ratio Analog-to-Digital Converters (ADCs) with approximately Sample Rates: Supports standard rates including 44.1k/48k/96k/192kHz for playback. Integrated Amplifiers: headphone amplifiers

The chip typically comes in a or 32-pin package depending on the specific sub-model. It requires a 3.3V or 1.5V power supply (depending on the rail) and connects to the system via the HDA Link (SDI/SDO signals, BCLK, SYNC, RST#). alc271x datasheet
