Features
Package Dimensions
• Current linear drive
unit: mm
• Control V type amplifier
3227-HSOP24
• 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 loses loss
