• Manufacturer Part Number: la6548nd
• 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 = 6V, VREF = 1.65V, unless otherwise 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, all the BTL amplifiers will be on, and the when
*4 : The 3.3V regulator voltage when the RESET pin goes from high to low.
*5 : The 3.3V regulator voltage difference between the RESET pin going from high to low the RESET pin going from low to high. That is, the hysteresis.
