Details: Product pin definition and function: CS: chip select (floating or high, boot; low, shutdown) IN-: audio signal input negative N +: audio signal input positive GND: Power ground VCC: Positive power supply SP +: audio signal output positive, then horn + SP-: audio signal output positive, then speaker - Precautions: 1. Power supply positive and negative can not be reversed, the power supply voltage can not exceed 5.5V, as long as there is one case, IC burned; 2. The chip has a high gain buffer, can not change any component parameters on the board, does not meet the parameters will lead to IC damage; 3. Enter the line as far as possible with a shielded line, you can play a role in anti-interference, to eliminate the clutter current sound. Specifications: Input impedance: 46k Ω Output impedance: 8 ~ 4 Ω Quiescent current: 3mA (5v power supply) Shutdown current: <0.1mA (5v power supply) Recommended sound: 3 ~ 10w Signal to noise ratio: 95bB Harmonic Distortion: <0.1% Frequency response range: 30Hz ~ 20kHz Operating temperature: -40 ~ 85 Cooling volume: no heat dissipation Protection function: no protection function Note: Gain is suitable for computer use Output power: 3w THD + N = 10% (4Ω, 5v) 1.8w THD + N = 10% (8Ω, 5v) 2.5w THD + N = 1% (4Ω, 5v) 1.4w THD + N = 1% (8Ω, 5v)
