CONFIDENTIAL ES9038Q2M 32-Bit Stereo Low Power Audio DAC Datasheet Analog Reinvented 32 The ES9038Q2M SABRE Reference DAC is a very high-performance, 32-bit, stereo audio D/A converter designed for: audiophile-grade power sensitive applications such as digital music players, Blu-ray players, audio pre-amplifiers and A/V receivers, and professional applications such as recording systems, mixer consoles and digital audio workstations. Using the critically acclaimed ESS patented 32-bit HyperStream II DAC architecture and Time Domain Jitter Eliminator, the ES9038Q2M delivers a DNR of up to 128dB and THD+N of 120dB, a performance level that will satisfy the most demanding audio enthusiasts. The ES9038Q2M handles up to 32-bit 768kHz PCM, DSD256 via DoP and native DSD512 data in master or slave timing modes. Custom sound signature is supported via a fully programmable FIR filter with 7 presets. Residual distortion from suboptimal PCB components and layout can be minimized using E S90 38Q 2 Ms unique THD compensation circuit, while chip-to-chip gain variation is minimized via a built-in auto gain calibration circuit. 32 The ES9038Q2M SABRE Reference DAC sets the standard, SABRE SOUND , for HD audio performance, typically consumes 40mW in normal operation mode (1.3mW in standby mode), and comes in an easy-to-use 30-QFN (3mm x 5mm) package.
