Instructions for Using SSM2164 (SMD):

1. Power Supply:

   • Connect the VCC pin to a stable 4.5V to 5.5V power supply.
   • Ensure the GND pin is connected to the system ground.

2. Input Connections:

   • Connect the differential input signals to the IN+ and IN- pins.
   • The input impedance is 10 kΩ, so ensure the source impedance is compatible.

3. Output Connections:

   • Connect the output signal to the desired load.
   • The output can swing from 0V to VCC - 1.2V.
   • Ensure the load does not exceed the maximum output current of 30 mA.

4. Biasing:

   • The device may require biasing for optimal performance. Refer to the datasheet for specific biasing circuits.

5. Thermal Management:

   • The operating temperature range is -40°C to 85°C. Ensure proper heat dissipation if operating near the upper limit.
   • Store the device within the storage temperature range of -65°C to 150°C.

6. Signal Integrity:

   • To maintain signal integrity, use short and well-shielded cables for input and output connections.
   • Use bypass capacitors (e.g., 0.1 μF) close to the VCC and GND pins to filter out noise.

7. Testing:

   • Before finalizing the design, test the device under various conditions to ensure it meets the required performance specifications.
   • Measure the SNR and THD to verify the audio quality.

8. Handling:

   • Handle the device with care to avoid static discharge, which can damage the sensitive components.
   • Follow standard ESD (Electrostatic Discharge) precautions during handling and installation.

9. Compliance:

   • Ensure that the design complies with relevant safety and regulatory standards for your application.
