Instructions for Use
Power Supply:
- Ensure the supply voltage (VDD) is within the range of 4.75V to 5.25V.
- Use a stable and clean power source to avoid noise and instability.
Quiescent Current:
- The typical quiescent current is 60mA. Ensure your power supply can handle this current without significant voltage drop.
Output Power:
- The maximum output power is 3.5W into an 8Ω load. Do not exceed this limit to avoid damage to the device or the speaker.
Efficiency:
- The typical efficiency is 85% at full power. This indicates that the device is highly efficient and will generate minimal heat.
Signal-to-Noise Ratio (SNR):
- The SNR is 95dB, indicating a high-quality audio signal with minimal background noise.
Total Harmonic Distortion + Noise (THD+N):
- At 1kHz and 1W into an 8Ω load, the THD+N is 0.01%, ensuring clear and distortion-free audio.
Input Sensitivity:
- A differential input voltage of 0.2Vrms is required for 1W output into an 8Ω load. Adjust the input signal level accordingly.
Input Impedance:
- The differential input impedance is 10kΩ. Ensure the source impedance is much lower to avoid loading issues.
Operating Temperature:
- The device operates reliably between -40°C and 85°C. Avoid exposing the device to temperatures outside this range.
Storage Temperature:
- Store the device between -65°C and 150°C to ensure long-term reliability.
Package:
- The TAS5711PHPR is available in a TSSOP-20 package. Follow standard handling and soldering guidelines for surface-mount components.
Layout Considerations:
- Use a ground plane to minimize noise and improve thermal performance.
- Keep signal traces short and direct to reduce interference.
- Place decoupling capacitors close to the power pins to ensure stable operation.
Thermal Management:
- Ensure adequate heat dissipation by using a heatsink or thermal pad if necessary, especially when operating at high power levels.
Testing and Troubleshooting:
- Test the device under controlled conditions to verify performance.
- If issues arise, check for proper power supply, correct input signals, and appropriate load conditions.
