• Manufacturer Part Number: la6571
• Description: 5ch Driver For Mini Disk And Compact Disk
• Manufacturer: Sanyo Semiconductor Corporation

Electrical Characteristics at Ta = 25°C, V CC 1 = 5V, V CC 2 = 12V, VREF-IN = 1.65V, unless especially specified
*1. Current dissipation that is a sum of V CC 1 and V CC 2 at no load.
*2. Input AMP is a BUFFER AMP.
*3. Voltage difference between both ends of load (8Ω). Output saturated.
*4. Voltage difference between both ends of load (12Ω). Output saturated.
*5. The source of input OP-AMP is a constant current. (See the specified block diagram.)
*6. Output ON with MUTE: [H] and OFF with MUTE: [L] (HI impedance).
*7. Design guarantee value
