Using the ESS proprietary 32-bit Hyperstream1 ADC architecture, the SABRE 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.
32
For highest performance, the SABRE ADC series implements a 32-bit programmable decimation filter and outputs
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
32
SABRE ADC series supports synchronous SPDIF or I2S master/slave output, or asynchronous I2S slave output
relative to the master clock for up to 384kHz sample rate and consumes less than 200mW.
