Instructions for Use:

  1. Power Supply:

    • Ensure the power supply voltage (VDD) is within the specified range of 4.5V to 5.5V.
    • Use a stable and clean power source to avoid noise and distortion.
  2. Output Configuration:

    • The differential output voltage (VOD) should be set to the desired level, typically around 2.4V for optimal performance.
    • Adjust the output current (IOUT) to match the load requirements, ensuring it remains within the specified range of 0.8mA to 1.2mA.
  3. Signal Quality:

    • To achieve the best signal-to-noise ratio (SNR) and dynamic range (DR), ensure the output voltage is set to 2Vrms.
    • Minimize external noise sources to maintain low total harmonic distortion plus noise (THD+N).
  4. Thermal Management:

    • Operate the device within the recommended temperature range of -40°C to 85°C.
    • Store the device in a dry environment with temperatures between -65°C and 150°C.
  5. Power Consumption:

    • Monitor power consumption, which should not exceed 15mW under typical operating conditions.
  6. Layout and Grounding:

    • Use a well-designed PCB layout with proper grounding to minimize electromagnetic interference (EMI) and ensure stable operation.
    • Place decoupling capacitors close to the power pins to filter out high-frequency noise.
  7. Handling:

    • Handle the device with care to avoid damage from static electricity or physical stress.
    • Follow standard ESD (Electrostatic Discharge) precautions during handling and installation.
