500MHz, 3nV/√Hz, A_V≥ 10

Operational Amplifier

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 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.
