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
chip-to-chip gain variation is minimized via a built-in auto gain calibration circuit.
The ES9038Q2M SABRE32 Reference DAC sets the standard, SABRE SOUNDTM, 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.
