Gain-Bandwidth: 150MHz

TheLT1221isaveryhighspeedoperationalamplifierwith

superior DC performance. The LT1221 is stable in a noise

gain of 4 or greater. It features reduced input offset

voltage, lower input bias currents 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. Thehighgainandfastsettlingtimemakethecircuit

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.
