FEATURE

The LT1208/LT1209 are dual and quad very high speed

operational amplifiers with excellent DC performance. The

LT1208/LT1209 feature reduced input offset voltage and

higher DC gain than devices with comparable bandwidth

and slew rate. Each amplifier is a single gain stage with

outstanding settling characteristics. The fast settling time

makes the circuit an ideal choice for data acquisition

systems. Each output is capable of driving a 500

Ω load to

±12V with ±15V supplies and a 150Ω load to ±3V on ±5V

supplies. The amplifiers are also capable of driving large

capacitive loads which make them useful in buffer or cable

driver applications.

The LT1208/LT1209 are members of a family of fast, high

performance amplifiers that employ Linear Technology

Corporation’s advanced bipolar complementary

processing.
