AT1201 Flagship Audio A/D Converter
The AT1201 is a 2-channel A/D converter designed for the most uncompromising high performance systems in the audio and test & measurement markets.
Using proprietary multi-bit sigma-delta modulation, the AT1201 provides the industry's highest dynamic range, excellent THD, and sampling rate of up to 384kHz. On-chip digital filters are designed for perceptually transparent response at all four sampling rates: 48kHz, 96kHz, 192kHz, and 384kHz. The filters can be bypassed to bring out multi-bit modulator outputs or DSD outputs directly to pins to enable the use of an external filter. Each of the three output modes (PCM, DSD, and multi-bit) can be enabled independently of the others, potentially allowing all three to be active simultaneously.
