USB ASIO Sound Card 192K Play and Recording DAC Module Drive-free Cellphone Raspberry Pi Adapter Measurement Card

Features:
- Using CS5341 chip, it supports 192K/24bit, the nominal signal-to-noise ratio in the manual is 105dB, and the actual measurement is shown in the figure below.
- Adopt 5 power supply with overvoltage, overcurrent and short circuit protection.
- The input stage adopts the rail-to-rail op amp LME49721, which is much better than directly inputting the ADC without an op amp signal.
- Use chip inductors to build a π-type filter circuit, which greatly reduces power supply noise.
- A voltage regulator tube is added to the ADC input port to prevent the input signal from being overloaded.
- Although the circuit board is small, 7 tantalum capacitors are still inserted to ensure the filtering effect.
- For IIS supports IIS mode and LJ mode, and supports slave mode by default. Most of the IIS clock is provided by the USB interface.
- The maximum input is 5Vpp, which can be compatible with mobile phones, TV series, CD players, etc., and its input can be customized, with a maximum input of 10Vrms.
- ES9023 module output, maximum output 5Vpp, distortion 0.002%.
- Support line or MIC input, switch by DIP switch.
- New revision and upgrade, size update, higher indicators, acrylic protection.
- Line output and input docking, using RMAA6.4.4 test indicators as shown below.
- The test uses the store's USB sound card, the signal is generated by the AP, and uses the recording software for Cooledit.

Package Included:
