192kHz/24bit USB ASIO Audio Module: CS5341 ADC + ES9023 DAC, Low Noise, Overvoltage Protection

Compact USB Audio Interface: CS5341+ES9023 – Product Advantages & Features

High-Precision Audio Chips & Custom Circuit Design

• ADC (CS5341): Supports 192kHz/24-bit sampling with a 105dB SNR (per datasheet). Real-world performance exceeds official reference designs, verified by professional testing equipment.
• DAC (ES9023): Delivers 5Vpp max output with 0.002% THD, ensuring clean, high-fidelity audio reproduction.
• Optimized Input Stage: Uses rail-to-rail op-amp (LME49721) to prevent distortion from direct ADC input, enhancing dynamic range.

Professional Power Management & Anti-Interference Design

• 5V Safe Power Supply: Integrates overvoltage, overcurrent, and short-circuit protection to safeguard devices.
• π-Type Filter Circuit: Low-noise power path with surface-mount inductors and 7 tantalum capacitors for deep filtering, ensuring ultra-pure power delivery.
• ADC Input Protection: Zener diodes prevent overload, compatible with 5Vpp sources (e.g., phones, TVs, CD players). Customizable for 10Vrms input.

Flexible Interface & Mode Support

• I2S/LJ Dual Modes: Default slave mode with USB-derived clock, compatible with embedded systems like Raspberry Pi.
• Input Switching: Supports line/MIC input via dip switch for versatile scenario adaptation.
• Modular Compatibility: Seamlessly interfaces with sound card modules (e.g., SA9023, SA9123L, SA9226) for scalable expansion.

Real-World Testing & Structural Optimization

• RMAA 6.4.4 Certified: Transparent line-in/out testing metrics for reliable performance validation.
• Upgraded Acrylic Enclosure: Compact redesign with enhanced EMI shielding.
• DIY-Friendly: Offers technical support and customization services for research, audio production, and hobbyist projects.
