Instructions for STA3698WS

  1. Power Supply Connection:

    • Connect the VDD pin to the positive terminal of your power supply.
    • Connect the GND pin to the negative terminal of your power supply.
  2. Input Signal Connection:

    • Connect the input signal to the IN pin. Ensure the input signal level is within the specified range (100 mVrms to 300 mVrms).
  3. Output Load Connection:

    • Connect the speaker or load to the OUT pin. The maximum output power per channel is 2W.
  4. Standby Mode:

    • To put the device into standby mode, apply a low logic level (less than 0.4V) to the SD (Shutdown) pin. This will reduce the quiescent current to approximately 0.1 μA.
  5. Thermal Management:

    • Ensure adequate heat dissipation by mounting the device on a heatsink if operating at high power levels. The device has built-in thermal protection that activates at 150°C.
  6. Protection Features:

    • The device includes overvoltage, undervoltage, short-circuit, and thermal protection. These features help prevent damage under abnormal operating conditions.
  7. Frequency Response:

    • The device maintains a flat frequency response from 20 Hz to 20 kHz, suitable for most audio applications.
  8. Signal-to-Noise Ratio:

    • The high SNR of 90 dB ensures minimal background noise, providing clear audio output.
  9. Total Harmonic Distortion:

    • The THD is typically 0.1% at 1 kHz and 1W output, ensuring high-fidelity audio reproduction.
  10. Operating Conditions:

    • Ensure the operating conditions (voltage, current, temperature) remain within the specified limits to avoid damage and ensure reliable operation.
