Allowable power dissipation, Pd max – W
• Current linear drive • Control V type amplifier • Separate power supply for output upper side bias circuit allows low output saturation by boosting this power supply only (useful for 5V power supply types).
• Upper side current detection technique reduces loss
voltage of current detection resistor.
Voltage effect of this resistor reduces internal power dissipa...
