LT1222
500MHz, 3nV/√Hz, AV ≥ 10
Operational Amplifier U FEATURES DESCRIPTIO ■ The LT®1222 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 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. The compensation node can also be used to clamp the output swing. ■
