32-bit Stereo Mobile Audio DAC

The SABRE9018C2M SABRE32 Reference DAC is a high-performance 32-bit, 2-channel audio D/A converter targeted for audiophile-grade portable applications such as mobile phones and digital music players, consumer applications such as Blu-ray players, audio pre-amplifiers and A/V receivers, as well as professional applications such as recording systems, mixer consoles and digital audio workstations.

Using the critically acclaimed ESS patented 32-bit HyperStream® DAC architecture and Time Domain Jitter Eliminator, the SABRE9018C2M SABRE32 Reference DAC delivers a DNR of up to 127dB and THD+N of  –120dB, a performance level that will satisfy the most demanding audio enthusiasts.

The SABRE9018C2M SABRE32 Reference DAC’s 32-bit HyperStream® architecture can handle up to    32-bit 384kHz PCM data via I2S, DSD-11.2MHz data as well as mono mode for highest performance applications.  Both synchronous and ASRC (asynchronous sample rate conversion) modes are supported.

The SABRE9018C2M SABRE32 Reference DAC comes in 25-Ball WLCSP package and consumes less than 40mW in normal operation mode (< 1mW in standby mode).

The SABRE9018C2M SABRE32 Reference DAC sets the standard for HD audio performance, SABRE SOUNDTM, in an easy-to-use form factor for today’s most demanding digital-audio applications.
