Product introduction:
ES9028 uses patented Hyperstream architecture and time-domain jitter cancellation technology to achieve jitter-free recording quality with a dynamic range of 112 dB.
Due to the negative voltage generated by the charge pump integrated in the chip, ES9028 can directly output 2Vrms with reference ground wire under single power supply, eliminating the coupling capacitance of DC voltage isolation. Moreover, the output amplitude can be set to less than 2Vrms level by resistance according to actual needs. The noise of switching machine can also be completely suppressed.
Product detail: 
All parts of this product are original, plain, pure quality; the use of high-quality original parts is not only to ensure safety and quality, long service life, but also to ensure that the actual performance can achieve the design goals. Pursuing first-class quality is our consistent aim.
1. Using original SA9023 ES9028K2M
2. The main circuit of electrolytic capacitor signal adopts Panasonic electrolytic capacitor imported from Japan, which guarantees strong and continuous power support.
3. PCB uses 1.6mm thick double panel, 2.0A thick copper, tin spraying process to ensure good passing performance of large and small currents. First-class PCB quality.
4. Supporting maximum 24-bit 96K sampling rate, supporting: 33K, 44.1K, 48K, 88.2K, 96K sampling rate.
5. PCB Size: 80*61.5MM
