32-bit Stereo Mobile DAC with Headphone Amplifier & Output Switch

The SABRE9018Q2C SABRE32 Reference DAC is a high-performance 32-bit, 2-channel audio D/A converter with headphone amplifier and output switch.  The SOC is designed 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 SABRE9018Q2C SABRE32 Reference DAC delivers a DNR of up to 121dB and THD+N of  –115dB, a performance level that will satisfy the most demanding audio enthusiasts.

The SABRE9018Q2C 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 SABRE9018Q2C SABRE32 Reference DAC sets the standard for HD audio performance, SABRE SOUNDTM, in an easy-to-use 40-pin QFN for today’s most demanding digital-audio applications.
