1 / 65 page  CONFIDENTIAL Analog Reinvented ES9038Q2M 32-Bit Stereo Low Power Audio DAC Datasheet ESS TECHNOLOGY, INC. 237 South Hillview Drive, Milpitas, CA 95035, USA Tel (408) 643- 8800 • Fax (408) 643-8801 FEATURE DESCRIPTION Patented 32-bit HyperStream ® II DAC o +128dB DNR o –120dB THD+N o Industry’s highest performance 32-bit low power audio DAC with unprecedented dynamic range and ultra-low distortion o Supports both synchronous and ASRC (asynchronous sample rate converter) modes Patented Time Domain Jitter Eliminator o Unmatched audio clarity free from input clock jitter 64-bit accumulator & 32-bit processing o Distortion free signal processing Integrated DSP Functions o Click-free soft mute and volume control o Programmable automute o De-emphasis for 32kHz, 44.1kHz, and 48kHz sampling Customizable output configuration o Stereo or Mono output in current or voltage mode based on performance criterion I2C control o Allows software control of DAC features 30-QFN package o Minimizes PCB footprint 40mW operating power consumption 1.3 mW standby power o Maximizes battery life Versatile digital input o Supports SPDIF, PCM (I2S, LJ 16-32-bit), DoP or DSD input o Supports up to 768kHz PCM, DSD256 via DoP and native DSD1024 Customizable filter characteristics o 7 presets or user programmable filters for custom sound signature o Bypassable oversampling filter THD compensation o Minimize distortion from external PCB components and layout Dedicated HPA Control o Power down HPA (supports auto shutdown at zero input for lower power) o Selects HPA auxiliary input o Programmable HPA charge pump frequency Auto Gain Calibration o Minimize chip-to-chip gain variation Clock Gearing o Reduce operating frequency for lower sampling rate to reduce power consumption The ES9038Q2M SABRE32 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 ES9038Q2M’s unique THD compensation circuit, while chip-to-chip gain variation is minimized via a built-in auto gain calibration circuit. The ES9038Q2M SABRE32 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. |
