32-bit High Performance Audio ADC

Product Brief

Analog Reinvented

The SABRE³²ADC series is the world’s highest performance 32-bit analog-to-digital (A/D) converter solution targeted

for consumer applications such as audio pre-amplifier, audio processor, A/V receiver and professional audio

applications such as recording systems, mixer consoles and digital audio workstations.

32ꢀbit Stereo ADC

384kHz

Using the ESS proprietary 32-bit Hyperstream ADC architecture, the SABRE³²Reference 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 SABRE³²ADC 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

SABRE³²ADC 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.
