Instructions for TPA3111D1PWPR
Supply Voltage:
- Ensure the supply voltage (VDD) is within the range of 4.5V to 18V.
- Use a stable power supply to avoid fluctuations that can affect performance.
Quiescent Current:
- The typical quiescent current is 12mA at VDD = 5V. This value may vary slightly depending on the operating conditions.
Output Power:
- The device can deliver up to 3.5W continuous average output power per channel into an 8Ω load with less than 1% THD+N.
Efficiency:
- The efficiency is typically 90% at 1W output power into an 8Ω load at VDD = 5V. High efficiency reduces heat generation and extends battery life in portable applications.
Signal-to-Noise Ratio (SNR):
- The SNR is 105dB at VDD = 5V, ensuring high audio quality with minimal background noise.
Total Harmonic Distortion plus Noise (THD+N):
- The THD+N is 0.05% at 1W output power, indicating low distortion and clean audio output.
Input Sensitivity:
- An input voltage of 0.775Vrms is required to achieve the rated output power.
Input Impedance:
- The input impedance is 10kΩ at 1kHz, making it compatible with a wide range of audio sources.
Shutdown Current:
- In shutdown mode, the current consumption is reduced to 1μA, which is useful for power-saving applications.
Operating Temperature:
