® The LT 1222 is a low-noise, very high-speed operational amplifier with excellent DC performance. The LT1222 is stabilized in a closed loop where noise gain is greater than or equal to 10 without compensation, or where the bandwidth and slew rate are lower in cost can be compensated externally. It features reduced input offset voltage, low input bias current, low noise, and a high DC gain ratio with device-comparable bandwidth and slew rate. The circuit is a single gain stage that includes a proprietary DC gain boost circuit for high-speed precision. High gain and fast settling times make it ideal for circuit data acquisition systems. The circuit is also capable of driving capacitive loads, which makes it useful for buffer or cable drive applications. It can also be used to compensate for the output swing of the node clamps.

The LT1222 is a fast, high-performance amplifier that is part of a family of advanced complementary bipolar processing from Linear Technology. For applications with stable unity gain, the LT1220 can be used with the LT1221 with a gain of 4 or more.
