ES9280APRO Datasheet | ESS Technology

feature -rich 32-bit, 2-channel USB audio D/A converter with headphone amplifier, PLL, Jack Detect, 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 (USB DACs and A/V receivers). Using the critically acclaimed ESS patented Hyper Stream® II QUAD DAC™ architecture and Time Domain Jitter Eliminator, and advanced SABRE32® technology, the ES9281A/80A PRO delivers a performance level that will satisfy the most demanding audio enthusiast. The versatile audio input port accepts PCM, DSD, Do P, SPDIF and MQA- formats. The integrated SABRE DAC supports up to 32-bit 384k Hz PCM, 96k SPDIF and DSD1024 audio data via master/slave interface in synchronous and asynchronous sampling modes. The ES9281A/80A PRO is a licensed and standard-pliant MQA native hardware renderer. PCM Audio rates up to 768k Hz are supported for USB-to-I2S mode and Native DSD is also supported over USB up to DSD512. The integrated class-G SABRE Headphone Amp supports up to 2Vrms output. Programmable analog gain and integrated low-noise DAC reference regulator minimize noise gain at typical listening levels and reduce PCB area and BOM cost. The Jack Detect feature automatically wakes the device, accurately measures load impedance and prevents false positives due to moisture infiltration without any support from the application processor. Aux Mix mode allows analog signals to be seamlessly overlaid onto digital audio even during DSD, Do P or MQA- playback.
