DESCRIPTIO

S

FEATURE

The LT1225 is a very high speed operational amplifier with

excellent DC performance. The LT1225 features reduced

input offset voltage and higher DC gain than devices with

comparable bandwidth and slew rate. The circuit is a

single gain stage with outstanding settling characteristics.

The fast settling time makes the circuit an ideal choice for

data acquisition systems. The output is capable of driving

a 500

Ω load to ±12V with ±15V supplies and a 150Ω load

to

± 3V on ± 5V supplies. The circuit is also capable of

driving large capacitive loads which makes it useful in

buffer or cable driver applications.

The LT1225 is a member of a family of fast, high per-

formance amplifiers that employ Linear Technology

Corporation’s advanced bipolar complementary

processing.
