High Performance Stereo ADC

Full Description

The AT1201 is a 24-bit stereo A/D converter designed for the most uncompromising high performance audio systems.

Using proprietary multi-bit sigma-delta modulation, the AT1201 provides the industy'ís highest dynamic range, lowest THD and a sampling rate of up to 384kHz.

On-chip digital filters are designed for perceptually transparent response at all four sampling rate modes: 48kHz, 96kHz, 192kHz, and 384kHz.

Multi-bit modulator and DSD outputs enable the use of external filters, and all three outputs (PCM, DSD, and multi-bit) can be enabled simultaneously.

The AT1201 is ideally suited for applications in:

  • Digital Audio Mixing Consoles
  • Live Sound Production
  • Broadcast Studio Equipment
  • Effects Processors
  • Surround Sound Encoders
An Evaluation Board AT1201EVK is available for this product.
