The SABRE

32

Reference ADC

is a two-channel 32-bit analog-to-digital (A/D) converter 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.

Using the ESS proprietary 32-bit Hyperstream

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

outputs the full 32-bit resolution in I

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

The SABRE

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