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 500Ω 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.
