Gain-Bandwidth: 500MHz  
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. 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. The compen-  
sation 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.
