Instructions for AK4353VF

1. Power Supply Connection:

   • Connect the supply voltage (VDD) between 2.7V and 3.6V to the power pin.
   • Ensure a stable power supply with adequate decoupling capacitors close to the device.

2. Analog Output Configuration:

   • The analog output voltage range is from 0V to VDD. Design your circuit to handle this output range appropriately.

3. Signal-to-Noise Ratio (SNR):

   • For optimal performance, ensure that the input signal is within the specified range to achieve the best SNR of 115 dB.

4. Total Harmonic Distortion + Noise (THD+N):

   • Operate the device at 1kHz to achieve the typical THD+N of -95 dB.

5. Power Management:

   • In active mode, the device consumes approximately 8mA. Switch to standby mode to reduce power consumption to 0.2μA when not in use.

6. Channel Separation:

   • At 1kHz, maintain channel separation greater than 90dB to avoid crosstalk between channels.

7. Temperature Considerations:

   • The operating temperature range is from -40°C to 85°C. Ensure the device operates within this range to avoid damage or performance degradation.

8. Initialization and Control:

   • Refer to the datasheet for specific initialization sequences and control settings to configure the device according to application requirements.
