Functions

• 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 drop
caused by this resistor reduces internal power
dissipation of IC.
