Instructions for STA3698WS
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.
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).
Output Load Connection:
- Connect the speaker or load to the OUT pin. The maximum output power per channel is 2W.
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.
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.
Protection Features:
- The device includes overvoltage, undervoltage, short-circuit, and thermal protection. These features help prevent damage under abnormal operating conditions.
Frequency Response:
- The device maintains a flat frequency response from 20 Hz to 20 kHz, suitable for most audio applications.
Signal-to-Noise Ratio:
- The high SNR of 90 dB ensures minimal background noise, providing clear audio output.
Total Harmonic Distortion:
- The THD is typically 0.1% at 1 kHz and 1W output, ensuring high-fidelity audio reproduction.
Operating Conditions:
- Ensure the operating conditions (voltage, current, temperature) remain within the specified limits to avoid damage and ensure reliable operation.
