Instructions for Use:
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.
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.
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).
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.
Power Consumption:
- Monitor power consumption, which should not exceed 15mW under typical operating conditions.
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.
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.
