ES9039Q2M Product Datasheet

Feature List

The ES9039Q2M is a SABRE® 2 channel high performance digital to analog converter (DAC) with features and

performance including the new Hyperstream IV modulator that produced a very high-performance device that is well suited

for a variety of applications.

In addition to improved performance, the new ES9039Q2M SABRE DAC now supports the TDM audio interface, SPI (or

I²C) control interface and hardware modes for simplifying device configuration.

TDM, I²S including LJ & RJ, DSD & DoP audio interfaces are supported.

Sample rates up to 768kHz (@ 64FS Mode) with PCM data with 2 selectable digital filters to choose from and a

programmable filter for custom sound signatures. DSD rates up to DSD1024 (512 x 44.1kHz) are also supported.

Configuration Modes

The ES9039Q2M has 4 control programming modes. They are controlled by the state of the MODE pin (Pin 29).
