The ES9023 is a 24-bit stereo audio DAC with an integrated 2Vrms op-amp driver. Powered by the industry

proven SABRE DAC technology, the ES9023 combines best-sounding audio with lowest system cost and

highest performance into the ideal D/A converter for line-level output applications such as Blu-ray players,

CD/DVD players, set-top boxes, digital TVs and audio receivers.

With patented Hyperstream

studio quality audio with 112dB DNR.

Using an integrated charge pump to generate the negative supply, the ES9023 can operate from a single

AVCC supply to drive a ground-referenced 2Vrms output, eliminating the need for output dc-blocking

capacitors. Optionally, the output level can be adjusted by using an external resistor, allowing for output

level below 2Vrms. Pop-noise is eliminated through a comprehensive suppression on power up/down, mute,

reset, loss of power or clock. Dedicated control/status pins allow easy system integration without the need

for microcontroller programming.
