Feature: 1. Use SA9023 ES9028K2M chip, decoder board's installation is simple, not requires particularly complicated operations. Supports up to 24‑bit 96K sampling rate. 2. Printed circuit board uses a 1.6mm thick double‑sided board, 2.0 ounces of copper thickness and the entire process of tin plating keeps good current transfer performance. 3. The ES9023 uses patented Hyperstream architecture and time‑domain jitter cancellation technology to enable it to achieve jitter‑free recording‑level sound quality with a dynamic range of 112dB. 4. Because the charge pump integrated in the chip can generate a negative voltage, the ES9023 can directly output 2Vrms with reference to the ground line under a single power supply, eliminating the coupling capacitor of DC voltage isolation. 5. Moreover, the output amplitude can be set to a level less than 2Vrms through a resistor according to actual needs. Switch on / off noise can also be suppressed. Specification: Item Type: Decoder board Dynamic Range: 112dB. Sampling Rate: Supports up to 24-bit 96K sampling rate. Package List: 1 x Decoder Board
