LT1222CS8_1087420

The LT1222 is a low noise, very high speed operational amplifier with superior DC performance. The LT1222 is stable in a noise gain of 10 or greater without compensa- tion, or the part can be externally compensated for lower closed-loop gain at the expense of lower bandwidth and slew rate. It 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 compen-ation node can also be used to clamp the output swing.The LT1222 is a member of a family of fast, high perfor-mance amplifiers that employ Linear Technology Corporation's advanced complementary bipolar process-ing. For unity-gain stable applications the LT1220 can be used, and for gains of 4 or greater the LT1221 can be used.
