Product Description
E203
The DAC chip in the E203, the ES9039SPRO, was developed under the latest Hyperstream® IV architecture.
The ES9039SPRO features an 8-channel independent current output path, to align with this design, Cayin has implemented an 8-channel independent I/V (Current-to-Voltage) conversion circuit corresponding. It is followed by the LPF circuit to extract four fully-differential signals, which are then paired with a Buffer driver circuit.
