ES9038Q2M
32-Bit Stereo Mobile Audio DAC
Datasheet
The ES9038Q2M SABRE32 Reference DAC is a very high-performance, 32-bit, stereo audio D/A converter designed
for: audiophile-grade portable applications such as mobile phones, 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 129dB 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
w chip-to-chip gain variation is minimized via a built-in auto gain calibration circuit.
a The ES9038Q2M SABRE32 Reference DAC sets the standard, SABRE SOUNDTM, for HD audio performance, typically
p consumes 40mW in normal operation mode (1.3mW in standby mode), and comes in an easy-to-use 30-QFN (3mm x
w 5mm) package.
