Instructions for Use
Power Supply:
- Ensure the supply voltage (VCC) is within the range of 2.7V to 5.5V.
- Connect a decoupling capacitor (typically 10μF) between VCC and GND to stabilize the power supply.
Clock Configuration:
- The bit clock (BCK) should be set between 2.822MHz and 11.288MHz.
- The master clock (MCLK) should be an integer multiple of the bit clock.
Data Format:
- The AK4413EQ supports I2S, Left-Justified, Right-Justified, and DSD data formats.
- Configure the data format using the control register settings.
Signal Input:
- The differential input voltage should not exceed 2.0Vpp.
- Ensure the input signals are properly balanced and within the specified range.
Power Management:
- To enter standby mode, set the appropriate bit in the control register.
- In standby mode, the power consumption drops to approximately 0.5μA.
Temperature Considerations:
- Operate the device within the temperature range of -40°C to 85°C.
- Store the device within the same temperature range to avoid damage.
Signal-to-Noise Ratio (SNR):
- The SNR is measured with A-weighting over the frequency range of 20Hz to 20kHz.
- Ensure the system design minimizes external noise sources to achieve the best performance.
Total Harmonic Distortion + Noise (THD+N):
- The THD+N is measured at 1kHz with a 0dBFS signal level.
- Keep the signal path clean and avoid overdriving the inputs to maintain low distortion.
Channel Separation:
- The channel separation is measured over the frequency range of 20Hz to 20kHz.
- Proper layout and shielding can help improve channel separation.
Dynamic Range:
- The dynamic range is also measured with A-weighting over the frequency range of 20Hz to 20kHz.
- Optimize the analog front-end and back-end stages to maximize the dynamic range.
