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 HyperstreamTM architecture and Time Domain Jitter Eliminator, the ES9023 delivers jitter-free
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.
