Description: With OTG function, USB power supply& support external power supply
1 The USB receiving chip adopts the PCM2706 of the US TI company which is the most used by enthusiasts The 16BIT48K has no digital flavor of other high sampling chips
2: The decoding part adopts the latest US ESS9023 top decoding core. ES9023 is a 24-bit stereo audio digital-to-analog conversion chip (DAC) of ESS Company. It adopts the industry-leading SABRE digital-to-analog conversion technology. This chip sets the best sound quality. Cost-effective, making it an ideal choice for digital to analog conversion. The ES9023 uses a patented Hyperstream architecture and time-domain jitter cancellation technology to achieve jitter-free recording quality with a dynamic range of 112dB. Install the store A2 sound card, please install the 4 pin headers on the left! Do not connect positive and negative high voltage
3. Signal-to-noise ratio 112db, distortion -93db, direct output 2V RMS audio voltage, high frequency without burrs, low frequency is full.
4. ES9023 has its own internal negative voltage conversion, which can output 2V (RMS) signal, which can be directly used as a rear amplifier or a preamp headphone amplifier .
5. Distortion: THD+N: Component selection: The output uses German WIMA, adopts high-precision active crystal oscillator, line optimization design, 0 noise floor design, background is very quiet, upgrade PC sound card, easy to improve sound quality!
The ES9023 is a 24-bit stereo audio digital-to-analog converter (DAC) from ESS that integrates a 2Vrms output driver op amp. Using the industry's advanced SABRE digital-to-analog conversion technology, this chip combines the best sound quality and cost-effectiveness, making it an ideal choice for digital-to-analog conversion.
