LT1222CS8#PBF

LT1222 is a low noise, very high speed operational amplifier with superior DC performance. It 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. 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. It is used in applications such as wideband amplifiers, buffers, active filters, video and RF amplification, cable drivers, 8-, 10-, 12bit data acquisition systems.
