The American ES9023 is a single-ended output 24bit stereo audio digital-to-analog conversion DAC chip, which integrates a driver op amp with 2Vrms output. It adopts the industry's advanced SABRE digital-to-analog conversion technology; it combines sound quality and high cost performance, making it an ideal choice for digital-to-analog conversion.
ES9023 is not only a guarantee of safety and quality, but also a long service life, and more importantly, a strong guarantee that the actual performance can reach the design goal;
The patented Hyperstream architecture and time-domain jitter elimination technology are used internally, enabling it to achieve jitter-free recording-level sound quality, with a dynamic range of 112dB.
Schematic diagram:
The ES9023 combines the best audio with the lowest system cost and highest performance to 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.
American ESS DAC Chip - ES9023 Features:
①SabreADC and 2Vrms operational amplifier driver integration
②Patented Super Streaming and Jitter Elimination Architecture
③ Adjustable output level; ground reference output
④ Dedicated control/status pins
⑤I2S or left-aligned selection
⑥Soft mute enabled; zero detection output
⑦ Charge pump that provides negative power
⑧ Low power consumption in 16-SOP
The integrated charge pump in the chip can generate negative voltage, and can directly output 2Vrms with reference to the ground wire under a single power supply, eliminating the coupling capacitance of DC voltage isolation. Moreover, the output amplitude can be set to a level of less than 2Vrms through resistors according to actual needs; the switching noise can also be fully suppressed.
Dedicated control/status pins allow easy integration into systems without microcontroller control; no microcontroller programming is required.
ES9023 has high indicators, and the resulting decoder has good hifi indicators, excellent analysis, and good level.
