Alc271x Datasheet Verified 100%

To save space on cramped laptop motherboards, the ALC271X often integrates a bridge-tied load (BTL) Class-D amplifier. This allows it to drive internal speakers directly without needing a massive external amp, reducing the overall Bill of Materials (BOM) for manufacturers. 3. Noise Suppression and Echo Cancellation

The ALC271X provides transparent, studio-quality sound. It supports 16 to 24-bit audio data formats with sample rates covering for both playback and recording. The signal-to-noise ratio (SNR) on the DAC output is rated at 98 dB (A-weighting), which meets the stringent requirements for Windows Logo Program (WLP) certification for Windows XP, Vista, and Windows 7. For the recording path (ADC), the SNR is rated at 90 dB , ensuring clear voice capture. alc271x datasheet
