• Wide operating voltage range: 3-12V, suggestion 5V
• Speaker power: 05W-10W, suggestion 8W speaker is the best
• Low static power consumption, the quiescent current of approximately 2MA, ideal for battery-powered
• Low power consumption, updated within the chain gain adjustable,large supply voltage range, fewer external components and total are widely used, widely used tape recorders and radios being.
• On-board volume control potentiometer clockwise to increase the volume,with power indicator light.
