Low-power FDDI transimpedance amplifier
Product specification
SA5222
DESCRIPTION
The NE/SA5222 is a low-power, wide-band, low noise
transimpedance amplifier with differential outputs, optimized for
signal recovery in FDDI fiber optic receivers. The part is also suited
for many other RF and fiber optic applications as a general purpose
gain block.
FEATURES
• Extremely low noise:2.0pAń ǸHz
• 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
