■ Single 5 V supply
■ Large bandwidth: 180 MHz
■ Differential outputs
■ Low input/output impedances
■ High power supply rejection ratio
■ 28 kΩ differential transresistance
3. Applications
■ Fiber optic receivers, analog and digital
■ Current-to-voltage converters
■ Wide-band gain block
■ Medical and scientific Instrumentation
■ Sensor preamplifiers
■ Single-ended to differential conversion
■ Low noise RF amplifiers
■ RF signal processing
