Arda's audio products group is dedicated to
fulfilling the needs of professional and consumer audio
system manufacturers. Arda's Early Adopter Program
(EAP) gives our key customers a voice in the product
definition early on in the design and development
process, thereby ensuring a product that is ideally
suited to their needs.
The AT1201 is a stereo A/D
converter designed for the most uncompromising high
performance audio systems. Using proprietary multi-bit
sigma-delta modulation, the AT1201 provides the
industry's highest dynamic range, lowest 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.

The AT12612 is a high performance
low-power stereo A/D
converter that is pin-compatible with the AT1201.
Perceptually transparent on-chip digital filters
provide PCM output up to 192kHz.
The filters
can be bypassed to bring multi-bit
or DSD outputs directly to pins to enable the use of an
external filter. Each of the three output modes (PCM,

simultaneously.

The AT1401 is a differential 24-bit D/A
converter designed for ultra high performance audio
systems. High output current of ±15.5 mA
and compliance voltage of 625mVp-p help to maximize the SNR that can
be achieved in the system.
An on-board, low noise reference generator and
external resistor set the full scale current level. A pin
programmable DAC for fine tuning of the full scale output
allows easy matching of multiple devices for
multi-channel applications.
