• Single 5V supply
• Low supply current: 9mA
• Large bandwidth: 165MHz
• Differential outputs
• Low output offset
• Low input/output impedances
• High power-supply-rejection ratio: 55dB
• Tight transresistance control
• High input overload: 115µA
• ESD protected

APPLICATIONS
• FDDI preamp
• Current-to-voltage converters
