FEATURE

DESCRIPTION

s

The ES9068A is a feature-rich 32-bit, 2-channel audio D/A converter with PLL,ADC and support for both analog and digital mics, and

analog/digital mixing. It has been designed for professional applications (mixer consoles, digital audio workstations), audiophile-grade portable

applications (headphones, headphone adapters and digital music players), and consumer applications (DACs and A/V receivers).Using the

critically acclaimed ESS patented HyperStream® II architecture, QUAD DAC™ technology,Time Domain Jitter Eliminator, and advanced SABRE

HIFI® technology, the ES9068A delivers a performance level that will satisfy the most demanding audio enthusiast.

The versatile audio input port accepts PCM, DSD,DoP, SPDIF and MQA formats. The integrated SABRE DAC supports up to 32-bit 384kHz

PCM, 96k SPDIF and DSD1024 audio data via master/slave interface in synchronous and asynchronous sampling modes.ES9068A is a licensed

and standard-compliant MQA native hardware renderer.

Integrated low-noise DAC reference regulator reduces PCB area and BOM cost. Aux Mix modeallows analog signals to be seamlessly overlaid

onto digital audio even during DSD, DoP or MQA playback.ES9068A may be customized for any application with firmware-controlled behavior

and both volatile and non-volatile memory options.
