Instructions for AK5381ET-E2
Power Supply:
- Connect the supply voltage (VDD) between 2.7V and 5.5V.
- Ensure a stable power supply to avoid noise in the analog input signal.
Analog Input:
- The analog input voltage (VIN) should be within the range of 0 to VREF.
- Do not exceed the reference voltage (VREF) to prevent damage to the device.
Reference Voltage:
- Set the reference voltage (VREF) between 1.2V and 3.6V based on your application requirements.
- This voltage defines the full-scale range of the analog input.
Signal Processing:
- For optimal performance, use an analog input level of VREF/2.
- The device is optimized for a sampling frequency (fS) of 48kHz for best SNR and THD+N.
Power Management:
- Monitor the power consumption, which typically stays around 2.2mA at 3.3V and 48kHz sampling rate.
- Ensure adequate heat dissipation if operating near maximum temperature limits.
Operating Environment:
- Operate the device within the temperature range of -40°C to 85°C.
- Avoid exposing the device to environments outside this range to ensure reliable operation.
