●The LT1222CN8#PBF is a 500MHz very high speed Operational Amplifier with superior DC performance. The LT1222 is stable in a noise gain of 10 or greater without compensation or the part can be externally compensated for lower closed-loop gain at the expense of lower bandwidth and slew rate. This low noise amplifier features reduced input offset voltage, lower input bias currents, lower noise and higher DC gain than devices with comparable bandwidth and slew rate. The circuit is a single gain stage that includes proprietary DC gain enhancement circuitry to obtain precision with high speed. The high gain and fast settling time make the circuit an ideal choice for data acquisition systems. The circuit is also capable of driving capacitive loads which makes it useful in buffer or cable driver applications. The compensation node can also be used to clamp the output swing.
