• Manufacturer Part Number: la6541nd
• Description: For Cd Players And Recorders Four-channel Driver Ic
• Manufacturer: Sanyo Semiconductor Corporation

Recommended Operating Conditions at Ta = 25°C
Electrical Characteristics at Ta = 25°C, V CC 1 = V CC 2 = 8V, VREF = 2.5V, unless especially specified.
*1: These parameters are not tested.
*2: The gain from input to output when only the V IN * pins are used.
*3: The MUTE pin voltage when the output changes between the on and off states. When the MUTE pin is high,
*4: The 5V regulator voltage when the RESET pin goes from high to low.
*5: The 5V regulator voltage difference between the RESET pin going from high to low the RESET pin going from low
