ES9270 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, the ES9270 delivers a performance level that will satisfy the most demanding audio enthusiast. The versatile audio input port accepts PCM, DSD and Do P. The integrated SABRE DAC supports up to 32-bit 384k Hz PCM, and DSD audio data via master/slave interface in synchronous and asynchronous sampling modes. Audio rates of 384k Hz and Do P are supported over USB. 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 playback. ES9270 may be customized for any application with firmware-controlled behavior and both volatile and non-volatile memory options.
