LT1220

45MHz, 250V/µs

Operational Amplifier

FEATURES

DESCRIPTIO

The LT^®1220 is a high speed operational amplifier with

superior DC performance. The LT1220 features reduced

input offset voltage, lower input bias currents and higher

DCgainthandeviceswithcomparablebandwidthandslew

rate. The circuit is a single gain stage that includes

proprietary DC gain enhancement circuitry to obtain pre-

cisionwithhighspeed. Thehighgainandfastsettlingtime

make the circuit an ideal choice for data acquisition

systems. The circuit is also capable of driving large

capacitive loads which makes it useful in buffer or cable

driver applications.

The LT1220 is a member of a family of fast, high perfor-

mance amplifiers that employ Linear Technology

Corporation’s advanced complementary bipolar process-

ing. For applications with gains of 4 or greater the LT1221

can be used, and for gains of 10 or greater the LT1222 can

be used for increased bandwidth.
