General Description
The SPT231 Buffer/Amplifier is a wideband operational amplifier designed specifically for high-speed, low-gain applications. The SPT231 is based on a current feedback op amp topology-a unique design that both eliminates the gain-bandwidth tradeoff and permits unprecedented high-speed performance. (See table below.)

FEATUREs
■ 165MHz closed-loop – -3dB bandwidth
■ 15ns settling to 0.05%
■ 1mV input offset voltage, 10µV/°C drift
■ 100mA output current
■ Excellent AC and DC linearity
■ Direct replacement for CLC231

APPLICATIONs
■ Driving flash A/D converters
■ Precision line driving (a gain of 2 cancels matched-line losses)
■ DAC current-to-voltage conversion
■ Low-power, high-speed applications (50mW @ ±5V)
