Using the ESS proprietary 32-bit Hyperstream ADC architecture, the SABRE

32

Reference ADC delivers an

unprecedented DNR of 127dB and THD+N of −120dB in mono mode (or DNR of 124dB and THD+N of −118dB in

stereo mode), a performance level that will satisfy the most demanding audio enthusiasts.

For highest performance, the SABRE

the full 32-bit resolution in I2S mode, or 24-bit resolution in SPDIF mode. A digital high-pass filter is available for DC

removal. Additionally, a programmable 8-band biquad filter is implemented for RIAA or custom equalization. The

SABRE

relative to the master clock for up to 384kHz sample rate and consumes less than 200mW.
