AD1881A datasheet

Description :

The AD1881A is an analog front end for high performance PC audio applications. The AC’97 architecture defines a 2-chip audio solution comprising a digital audio controller, plus a high quality analog component that includes Digital-to-Analog Converters (DACs), Analog-to-Digital Converters (ADCs), mixer and I/O.

The main architectural features of the AD1881A are the high quality analog mixer section, two channels of ΣΔ ADC conversion, two channels of ΣΔ DAC conversion with Data Direct Scram-bling (D2S) rate generators. The AD1881A’s left channel ADC and DAC are compatible for modem applications supporting irra-tional sample rates and modem filtering requirements.
