Instructions

1. Power Supply:

   • Ensure the supply voltage (Vcc) is within the range of 2.7V to 5.5V.
   • Use a stable power source to avoid fluctuations that can affect performance.

2. Temperature Considerations:

   • The device operates optimally between -40°C and 85°C.
   • Store the device between -65°C and 150°C to ensure long-term reliability.

3. Output Current:

   • Each channel can provide up to 50mA of output current, with a typical value of 20mA.
   • Do not exceed the maximum output current to prevent damage to the device.

4. Quiescent Current:

   • The quiescent current (Iq) is typically 1.5mA and should not exceed 3.0mA.
   • Minimize quiescent current to reduce power consumption.

5. Output Voltage Swing:

   • The output voltage swing (Vos) is typically 0.2V, with a minimum of 0.1V and a maximum of 0.3V.
   • Ensure the load impedance is appropriate to achieve the desired output voltage swing.

6. Bandwidth:

   • The device has a typical bandwidth (BW) of 200kHz.
   • Use it in applications where this bandwidth is sufficient.

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

   • The SNR is typically 90dB, providing a high level of signal purity.
   • Use the device in audio or other applications requiring low noise.

8. Total Harmonic Distortion (THD):

   • The THD is typically 0.01%, indicating minimal distortion.
   • This makes the device suitable for high-fidelity applications.

9. Mounting and Handling:

   • Handle the device with care to avoid static discharge and physical damage.
   • Follow standard surface mount technology (SMT) procedures for mounting on PCBs.

10. Testing and Troubleshooting:

    • Test the device under specified conditions to ensure proper operation.
    • Refer to the datasheet for detailed troubleshooting tips and application notes.

By following these parameters and instructions, you can ensure optimal performance and reliability of the PCM69AU.
