Audio ADC breaks the Sampling Frequency Barrier

With sampling frequency of 384 KHz, direct access to multibit modular outputs and low latency filters the flagship Stereo A/D converter is designed to power top end, high performance audio systems.

With sampling frequency of 384 KHz, direct access to multibit modular outputs and low latency filters the flagship Stereo A/D converter is designed to power top end, high performance audio systems.


Using proprietary multi -bit sigma -delta modulation, the AT1201 provides the industry's highest dynamic range of 194 dB, and sampling range of 384 KHz. 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.

Designed for less demanding and lower power applications AT12612 is perfect for applications requiring the same high quality as AT1201 but lower sampling frequency and dynamic range.

A low power, high performance stereo A/D converter, the AT12612 provides a PCM output up to 192 KHz and a dynamic range of 120dB.

The AT12612 is pin compatible with the AT1201. For more details please visit the website.

Evaluation Kits:
The evaluation kits demonstrate the performance and features of the AT/1201AT12612. The kits provide several methods for generating data from the ADC including PCM outputs through the natively generated I2S or LJ streams, as well as using an on -board DIT to provide AES compliant output through an XLR interface, an electrical S/PDIF interface, and an optical S/PDIF interface.
The multibit modulator outputs and DSD outputs are available through headers on the board for interfacing to data acquisition equipment, an FPGA board, or a DSP processor.
