• Manufacturer Part Number: la6569
• Description: 5-channel Driver For Compact Disk Applications
• Manufacturer: Sanyo Semiconductor Corporation

Electrical Characteristics at Ta = 25°C, V CC 1 = V CC 2 = 8V, VREF = 1.65V, unless especially specified.
*1. Current dissipation that is a sum of V CC 1 and V CC 2 at no load.
*2. Design guarantee value.
*3. Input AMP is a BUFFER AMP.
*4. Voltage difference between both ends of load (8Ω). Output saturated.
*5. Output ON with MUTE : [H] and OFF with MUTE : [L] (HI impedance).
*6. The source of input OP-AMP is a constant current. As the 11kΩ resistance to the next stage is a load,
*7. Short (GND) brake used. SINK side output ON.
*8. 3.3VREG incorporates a drooping protection circuit and operated when the base current is 10mA (TYP).
*9. The output is 3.3V when the REG-EN pin is HIGH.
