Instructions for Use:

1. Power Supply: Connect the supply voltage (VCC) within the range of 2.7V to 5.5V. Ensure stable power supply to avoid audio distortion.
2. Quiescent Current Management: The device operates with a low quiescent current of 40μA at no load and VCC = 3V, which helps in extending battery life in portable applications.
3. Output Configuration: For optimal performance, connect an 8Ω load for output power testing. At VCC = 5V, the typical output power is 200mW with a 1% THD.
4. Efficiency Consideration: When operating at 20mW output power with VCC = 5V, the efficiency is typically 80%, ensuring minimal power loss.
5. Audio Quality: To achieve high-quality audio, note that the signal-to-noise ratio (SNR) is 95dB A-weighted at VCC = 5V, providing clear sound reproduction.
6. Distortion Control: Keep the total harmonic distortion (THD) at 0.05% when operating at 20mW output power and VCC = 5V for undistorted audio output.
7. Shutdown Mode: To minimize power consumption, use the shutdown feature by applying a voltage less than or equal to 0.4V to the shutdown pin (VSD), which reduces the current draw to 0.1μA.
